Moderation - A Warning from History (-1, Offtopic)

ringbarer (545020) | more than 12 years ago | (#3316778)

Visitors to the website [] will by now have surely heard of the act of Moderation. This is where a contributor's post can be 'Moderated' either positively or negatively, depending on how the Moderator perceives the value of the post. There is a sliding scale of total moderation points, from -1 to 5, along with snappy summaries of the reason for moderation, such as "Funny", "Insightful", or the ever popular "Troll". An additional benefit offered to Moderators is the ability to ban a poster from contributing, by negatively moderating enough of his postings in a 24 hour period.

In order to retain some level of fairness for the Slashdot population, the Slashdot Editors (adopting the role of 'Benevolent Dictators') have implemented a scheme whereby regular users of Slashdot, chosen essentially at random, are given the ability to act as Moderators.

This underlines an inherent flaw in the system. Psychological studies have shown that in any community, no matter how small, should a random sampling of people be given the slightest grasp of power, they will immediately abuse it. There is a primal, evolutionary desire in Man to place himself higher than his peers by whatever measurement they can muster. Slashdot Moderation provides the ideal means for which a man can prove himself more equal than others.

At the risk of invoking Godwin's Law at such an early point in my thesis, I have no choice but to compare Slashdot Moderation to the systematic genocide of the Jewish community in 1930's Germany.

A bold statement, I admit, and deliberately designed to shock, but I feel the statement is necessary. I shall now offer a more rational explanation, as well as a comparison of the parallels between Slashdot Culture, and the National Socialist regime.

First, some history. National Socialism did not spring up overnight. It grew from a feeling of national bitterness and resentment at the war reparations Germany was forced to make after World War One. Germany was a broken country, populated by desperate starving people. And to the desperate, an extreme ideology begins to seem like a rational choice.

The advent of new technology forces a paradigm shift in the way the beholders of that technology think. The Christianity Meme was made wide spread by the invention of the Gutenberg press. And the rise of National Socialism was made popular because of the invention of Cinema. Here we had a new means to control the flow of information to the populace, that they are willing to unquestioningly listen to due to the 'novelty factor' of moving pictures. It is no coincidence that some of the best Cinematography of the early 20th Century came out of the National Socialist propaganda machine.

Why is this the case? It is yet another fault of man that a new means of distributing memes is perceived, due to the 'newness' of the medium, to have a greater 'validity' than older media. Those harnessing new inventions have the power to win control of the hearts and minds of others.

With the tools in place, who should the National Socialists target? Clearly, as a counterpoint to Man's desire to hold power over others, there is also a desire to resent the success of others. If someone is successful, they reduce the self-worth of their beholders. Although times were harsh in Germany in the prelude to World War II, there were still successful inhabitants of that country. Possessing shrewd business acumen as well as the contacts in other countries needed to maintain support in such a poverty stricken and broken land, who else should deserve the wrath of the populace more than the Jews?

Fast-forward to the latter quarter of the 20th Century. Computing technology is focused in niche markets, and limited to big successful companies like IBM and Microsoft. As the markets were limited, there were also limited opportunities for employment. This gave rise to a rising number of college dropouts, seething with resentment and unable to relate to society beyond the staccato clatter of keyboards and the pallid green glow of an 80x24 text display, and lacking the basic business skills (and a smart suit) needed to secure employment at one of these companies.

At this time, a new invention was beginning to take hold in College campuses throughout the world. The Internet. As with the Gutenberg press and Cinema beforehand, this new technology would grow to spread one of the most virulent memes of the modern age - Open Source Software, created as the antithesis of successful business practise.

So, the parallels between the birth of Anti-Semetic National Socialism and the birth of Open Source Software have been made. Of course, it is easy to claim that A=B without providing further logical evidence in support. So, the next task of my thesis is to provide further parallels, and bring this discourse back to the initial focus on Slashdot Moderation.

Slashdot was conceived, in it's original 'Chips 'n' Dips' incarnation, as a vehemently anti-corporate Open Source website. Roughly 10-15 years down the line from the birth of Open Source, it has become saturated with propaganda, and now forms the centrepiece of the Open Source Development Network. An authority in it's field, Slashdot's success is in no small part due to the ability of the editors to 'pick and choose' valid news articles submitted by users, and present the same old tired "Open Source Good / Closed Source Bad" rhetoric time and time again, dabbling with anti-copyright and the right of the 'common man' to remove an artist's ability to gain compensation for the work. In essence, this is similar to the 'paring down' of artistic worth in 1930's Germany. If no-one is willing to contribute valid and vibrant art to the community, then all art shall become harsh and functional, possessing a certain intimidating aesthetic.

Which leads onto Open Source's shining achievement - Linux. This diatribe is not aimed towards Linux in particular, as it is a well-oiled, well-tuned machine. A technically adept Operating System, it is worthy of admiration by any rational man. The point of this thesis is not to attack the art produced by Open Source coders, which in itself is worthy, but to enlighten all as to the political processes behind the OSS movement.

By the same scale, it is hard to fault Mercedes for the technical excellence of the vehicles which were used by the National Socialist party. But the politics behind the party are what taint the image of Mercedes' vehicles of the era. The Swastika itself is a benign symbol, found this day in such diverse locations as Pokemon cards, but is permanently tainted with the history of the acts made under its auspice. In the same way, companies switching to Open Source solutions will begin to regard the Penguin with the same trepidation as their profits fall.

It should be worth noting at this point that IBM, previously one of the world's greatest companies, has begun reporting servere financial losses, no doubt due to its adoption of Open Source practises. This epoch-making event was NOT reported on Slashdot, even though articles were submitted.

And what of the other great company mentioned above? Microsoft, aka Micro$oft, Mickeysoft, Microshaft, Kro$oft, and many other derogatory and undeserved names. Throughout the previous 25 years, Microsoft has grown from strength to strength, again possessing shrewd business acumen as well as providing products that people want. This makes them the number one target for the OSS movement. Incapable of standing by their own merits, the OSS zealot would rather attack Microsoft as a priority than produce anything of worth for their community.

Slashdot Moderators, crazed with their limited new-found power, exhibit this behavior. It is a sad state of affairs that the majority of article moderations are negative. Where is the positive feedback and sense of social contribution? Nowhere to be found. Moderators are too focused on putting their peers down to make themselves appear superior, rather than doing the hard work and becoming better on their own terms.

As the National Socialists required a scapegoat, Slashdot Moderators require a constant stream of Postings to label '-1, Inferior'. Once a posting is reduced to the score of -1, it becomes invisible to the casual user. Again, this is a parallel to the Ghettoization of Germany upon the election of Hitler.

In essence this would not be so bad, were postings to be evaluated on their own terms. However, alongside the moderation of their postings, each user has a 'Karma' value, namely the sum of their worth to the Slashdot community. As a user's posts are moderated up or down, so their Karma fluctuates. As Karma becomes negative, a user's default posting score is reduced, until they are posting at a default of -1. Again, ghettoizing PEOPLE, not just their opinions.

This ghettoization is reinforced with the often fake belief that a negatively moderated post, and therefore the poster, is a "Troll". (Is it any wonder that such a name has been chosen to describe these people, invoking mental imagery of facial disfigurement and hooked noses?) As the Jews were accused of fraud, dishonesty and being subhuman animals, so too are Trolls accused of FUD, Crapflooding, and obfuscated links. Quite often, these 'undesirables' are capable of providing a valid insightful comment on a topic, but because it is in opposition to the Political dogma of Slashdot they are moderated back into their ghetto. The person becomes moderated, not their opinion.

This is just the thin end of the wedge. Although, as memes are transient, it is difficult to silence an opinion, it is trivial to silence a person. Upon the rise of National Socialism in Germany, the populace were motivated by propaganda into entering the Jewish Ghettos en masse with the sole purpose of causing as much damage as possible to Jewish businesses and residences. This parallels far too accurately with the Slashdot Editor's non-discouragement of the act of IP-banning. As mentioned above, this occurs when an individual user's postings are repeatedly moderated down in a short period. They then become incapable of posting any contributions themselves. In essence, they have been silenced, regardless of the worth of their postings.

Of course, the editors claim that Meta-Moderation is the panacea to solve this clear abuse of moderating privledge. But if a Meta Moderator is presented with a list of moderations that they disagree with, such as this targetted 'silencing' mentioned above, they cannot note them as such without in turn becoming an 'Undesirable' themselves, as too many Disagreements with the Moderation groupthink also result in loss of Karma.

Throughout all of this, the Editors have claimed a false level of detachment from the acts of moderation. In a same way, as the National Socialists gathered their power and began working on their Elite Political wing, The SS, they too remained detached from the civilians working in their name. Why? Because after inspiring the populace to such acts of violence through their propaganda, they could then claim that they were only giving the people what they want.

And then began the next stage of the atrocities. The Gestapo, Germany's secret police, were recruited from the best and the brightest of Germany's elite. As is the case now, the best and the brightest of society were often shunned and ostracized in society. In essence, the Gestapo were a tightly controlled 'Geek Army' of intelligent young men with a burning, seething resentment of normal society. The perfect psychological profile for the cause.

After all, give a normal man (with an active sex life) a gun and he will use it responsibly in self defence. Give a geek a gun and he will behave according to his sociopathic logic and hatred of the world he arrogantly presumes to be distant from. Ask yourself why Slashdot flat-out justified the murder of innocents at Columbine. And then ask yourself why, even for a brief moment, you almost began to sympathize with the killers after Jon Katz' manipulative and pseudo-emotive Hellmouth articles.

How this relates to Slashdot is clear. The majority of Slashdot posters are Sociopathic OSS zealots, unable through lack of social finesse or personal hygiene to mate regularly. Sexually and emotionally frustrated and with grudges to bear, incapable in their blinkered sense of self-righteousness of accepting any dissenting opinion than the OSS cause. Now give these people the opportunity to Moderate these dissenting opinions. Of course they are going to want to silence them, by any means necessary.

Now, the Slashdot Editors have admitted taking this silence of opinion into the next stage, by moderating whole swathes of 'undesirable' posts negatively. And then permanently banning anyone who moderates said posts back up from moderating EVER again! The result of this new policy? The few Moderators with any sense of fairness and decency are removed from the moderation pool, leaving the power ENTIRELY in the hands of the zealots. Clearly, positive moderation is discouraged under this regime, which is a direct parallel with the way the National Socialists moved their own sympathisers into positions of power throughout Europe.

So how does this compare to the genocide performed in Auschwitz and their ilk? I would like at this point to explain that in NO way do I wish to belittle the horrors that were performed in the name of National Socialism. The six million innocents killed were a cry of anguish from which humanity may never recover. And a vast distance in time and scope from a few banned posters on some shitty "My Favourite Links - now with comments" website. But these stories need to be retold before the horror is lost forever.

For the only thing that we learn from history is that we never learn anything from history. Time and time again, the St. Vitus dance is played out, we make the same mistakes, and we perpetually fail to see the warning signs.

So, moderators, the next time you moderate a rational, insightful post down, maybe because you disagree with it or because it's posted by a 'Known Troll', just ask yourself this...

"Am I really contributing to the Slashdot Community, or selfishly destroying it?"

I think the fact that a site like slashdot, which caters to you fucking nerds out there, can't even
survive without having to charge you for reading it, says alot about how much you fucks are worth to the rest of the world: ZERO.

This should serve as a wakeup call to all you nerds out there who think that working on your b0xen in your one bedroom apartment, posting useless shit to a useless web site like slashdot and reading about the newest version of OpenBSD that can run on your fucking Dreamcast console is a good way to go through life.

Just seal up the case with silicone and fill it with PCB. You should be able to get PCB for nothing at a toxic waste dump. No pumps or fans required, the oil will circulate in the case through convection. This is quiet and safe, since PCB doesn't burn and is pretty much non-toxic. It does cause cancer in rats though, but rats are sensitive creatures and can get cancer from anything...

Actually, my fridge spends most of the time off, and I'm pretty sure yours does too (unless you leave the door open all the time or something). The cooling in a fridge only kicks in as necessary (when you here it make a low buzzing sound as opposed to silent). A small fridge probably couldn't cool a computer fast enough to matter (particularly around the processor itself).

Okay, so his water pump is only designed to run for a max of 10 minutes before overheating. Since overclocked CPUs generate heat, an underclocked CPU must be able to absorb heat, right? RIGHT? Why not slap an old 286 onto the pump, underclock it to run at, oh, say, 2 Hz (not mHz, but plain ol' Hz) and the 286 will absorb all the excess heat off the pump! Voila! :-)

stoolpigeon (454276) | more than 12 years ago | (#3316924)

First off IANAP but this guy should talk to one.

He should take a look at some aquariums as well. That would take care of finding a pump that can run continually w/out overheating. I would think it has to be much cheaper than pumps built for remote controled submarines.

Some small compression fittings would take care of the tube problem. Maybe some o-rings instead of rubberbands on the outside. I can think of a few ideas that would involve more than just pressure on the outside of the tubing. (That's why he had such a tough time stopping the leaks- he tried to tackle it all from the outside)

Very nice box- a little tweaking and it would be very applicable for anyone.

Still, these designs look good, and with a better pump, I would love to see some long term tests with this.

Why water, try oil. (4, Insightful)

bluGill (862) | more than 12 years ago | (#3316929)

Water conducts electrisity. Well, pure water doesn't, but pure water will eat metal until it does conduct. That means you have to keep your water carefully sererate from everything else.

By contrast, oil doesn't conduct, doesn't disolve metal. Fill your case with oil, and you have better cooling than air, and much easier to deal with. (Note, oil isn't as good as water for heat capacity, but it is still better than air and has all the other advantages)

Re: Why water? (4, Funny)

Wingchild (212447) | more than 12 years ago | (#3316943)

Water cooling requires that the water, passing nearby a heat source, absorbs the heat and carries in on to a place where it can be safely transferred into the surrounding environment. The old Second Law, Energy can neither be created nor destroyed, etc etc.

So why would we opt for water, which would be a less than optimal coolant? Because hot water makes *coffee*. Imagine! You could have a water-cooled server *and a coffee machine* all in the same rackmount!

The possibilities are endless.

Why water? Why not mineral oil or something that's certain not to conduct electricity? It might not take heat away quite as fast as water does but it should still be a lot better than air.

I wonder whether liquid nitrogen is feasible. That would be a great cooling system for a Beowulf cluster: remove the cases, hard disks etc and just stack motherboards really close together in a big bathtub filled with cold liquid.

Re:Other liquids (1)

Good point. This was only Rob's second attempt at a home-made water cooling block. Our next will involve water cooling around a heatsink which should help dissipate the heat much further.. Mineral Oil would be a great idea too. Thanks for the suggestion :)

Re:Other liquids (2, Informative)

pkesel (246048) | more than 12 years ago | (#3317059)

You'll need a much more expensive pump to push mineral oil, or about anything but water. The extra viscosity will likely cause the pump to overheat. And the seals and such may decay with other materials.

One catches the unholiness of Christian means in flagranti by the simple process of putting the ends sought by Christianity beside the ends sought by the Code of Manu--by putting these enormously antithetical ends under a strong light. The critic of Christianity cannot evade the necessity of making Christianity contemptible.--A book of laws such as the Code of Manu has the same origin as every other good law-book: it epitomizes the experience, the sagacity and the ethical experimentation of long centuries; it brings things to a conclusion; it no longer creates. The prerequisite to a codification of this sort is recognition of the fact that the means which establish the authority of a slowly and painfully attained truth are fundamentally different from those which one would make use of to prove it. A law-book never recites the utility, the grounds, the casuistical antecedents of a law: for if it did so it would lose the imperative tone, the "thou shalt," on which obedience is based. The problem lies exactly here.--At a certain point in the evolution of a people, the class within it of the greatest insight, which is to say, the greatest hindsight and foresight, declares that the series of experiences determining how all shall live--or can live--has come to an end. The object now is to reap as rich and as complete a harvest as possible from the days of experiment and hard experience. In consequence, the thing that is to be avoided above everything is further experimentation--the continuation of the state in which values are fluent, and are tested, chosen and criticized ad infnitum. Against this a double wall is set up: on the one hand, revelation, which is the assumption that the reasons lying behind the laws are not of human origin, that they were not sought out and found by a slow process and after many errors, but that they are of divine ancestry, and came into being complete, perfect, without a history, as a free gift, a miracle . . . ; and on the other hand, tradition, which is the assumption that the law has stood unchanged from time immemorial, and that it is impious and a crime against one's forefathers to bring it into question. The authority of the law is thus grounded on the thesis: God gave it, and the fathers lived it.--The higher motive of such procedure lies in the design to distract consciousness, step by step, from its concern with notions of right living (that is to say, those that have been proved to be right by wide and carefully considered experience), so that instinct attains to a perfect automatism--a primary necessity to every sort of mastery, to every sort of perfection in the art of life. To draw up such a law-book as Manu's means to lay before a people the possibility of future mastery, of attainable perfection--it permits them to aspire to the highest reaches of the art of life. To that end the thing must be made unconscious: that is the aim of every holy lie.--The order of castes, the highest, the dominating law, is merely the ratification of an order of nature, of a natural law of the first rank, over which no arbitrary fiat, no "modern idea," can exert any influence. In every healthy society there are three physiological types, gravitating toward differentiation but mutually conditioning one another, and each of these has its own hygiene, its own sphere of work, its own special mastery and feeling of perfection. It isnot Manu but nature that sets off in one class those who are chiefly intellectual, in another those who are marked by muscular strength and temperament, and in a third those who are distinguished in neither one way or the other, but show only mediocrity--the last-named represents the great majority, and the first two the select. The superior caste--I call it the fewest--has, as the most perfect, the privileges of the few: it stands for happiness, for beauty, for everything good upon earth. Only the most intellectual of men have any right to beauty, to the beautiful; only in them can goodness escape being weakness. Pulchrum est paucorum hominum: goodness is a privilege. Nothing could be more unbecoming to them than uncouth manners or a pessimistic look, or an eye that sees ugliness--or indignation against the general aspect of things. Indignation is the privilege of the Chandala; so is pessimism. "The world is perfect"--so prompts the instinct of the intellectual, the instinct of the man who says yes to life. "Imperfection, what ever is inferior to us, distance, the pathos of distance, even the Chandala themselves are parts of this perfection. "The most intelligent men, like the strongest, find their happiness where others would find only disaster: in the labyrinth, in being hard with themselves and with others, in effort; their delight is in self-mastery; in them asceticism becomes second nature, a necessity, an instinct. They regard a difficult task as a privilege; it is to them a recreation to play with burdens that would crush all others. . . . Knowledge--a form of asceticism.--They are the most honourable kind of men: but that does not prevent them being the most cheerful and most amiable. They rule, not because they want to, but because they are; they are not at liberty to play second.--The second caste: to this belong the guardians of the law, the keepers of order and security, the more noble warriors, above all, the king as the highest form of warrior, judge and preserver of the law. The second in rank constitute the executive arm of the intellectuals, the next to them in rank, taking from them all that is rough in the business of ruling-their followers, their right hand, their most apt disciples.--In all this, I repeat, there is nothing arbitrary, nothing "made up"; whatever is to the contrary is made up--by it nature is brought to shame. . . The order of castes, the order of rank, simply formulates the supreme law of life itself; the separation of the three types is necessary to the maintenance of society, and to the evolution of higher types, and the highest types--the inequality of rights is essential to the existence of any rights at all.--A right is a privilege. Every one enjoys the privileges that accord with his state of existence. Let us not underestimate the privileges of the mediocre. Life is always harder as one mounts the heights--the cold increases, responsibility increases. A high civilization is a pyramid: it can stand only on a broad base; its primary prerequisite is a strong and soundly consolidated mediocrity. The handicrafts, commerce, agriculture, science, the greater part of art, in brief, the whole range of occupational activities, are compatible only with mediocre ability and aspiration; such callings would be out of place for exceptional men; the instincts which belong to them stand as much opposed to aristocracy as to anarchism. The fact that a man is publicly useful, that he is a wheel, a function, is evidence of a natural predisposition; it is not society, but the only sort of happiness that the majority are capable of, that makes them intelligent machines. To the mediocre mediocrity is a form of happiness; they have a natural instinct for mastering one thing, for specialization. It would be altogether unworthy of a profound intellect to see anything objectionable in mediocrity in itself. It is, in fact, the first prerequisite to the appearance of the exceptional: it is a necessary condition to a high degree of civilization. When the exceptional man handles the mediocre man with more delicate fingers than he applies to himself or to his equals, this is not merely kindness of heart--it is simply his duty. . . . Whom do I hate most heartily among the rabbles of today? The rabble of Socialists, the apostles to the Chandala, who undermine the workingman's instincts, his pleasure, his feeling of contentment with his petty existence--who make him envious and teach him revenge. . . . Wrong never lies in unequal rights; it lies in the assertion of "equal" rights. . . . What is bad? But I have already answered: all that proceeds from weakness, from envy, from revenge.--The anarchist and the Christian have the same ancestry. . . .

Rubber bands? (1)

heneon (570292) | more than 12 years ago | (#3316960)

In my experience rubber bands get weak, especially in warm places, and eventually break. I would not like to have a computer running when the "insulation" breaks and drowns the motherboard. Then again, this thing is supposed to take the heat out so maybe it's cool enough.

Personal Experience (3, Informative)

quantax (12175) | more than 12 years ago | (#3316971)

As someone who has built his own homemade watercooler, this setup is very jury-rigged and definately not recommended for any sort of serious long term cooling. The copper-tube inlets need to be replaced w/ brass fittings to avoid leakage, and the rubber bands should be replaced with cheap and much more effective band clamps. This waterblock design is not effective water-distrobution wise either as the water is not forced to flow through out the entire design. This would let the side furthest the inlets get hot due to poor water flow. An open chamber is only good for small waterblocks. Lastly, using thread to attach a waterblock to the cpu is ghetto as hell. Either quickly engineer a heatsink clamp yourself, or just look up a guide on the net for this, its pretty simple. Watercooling is one of those things that can be done many different ways, but this particular method is a little more 'amature' than is recommended to put on any piece of equipment that you value. If you are going to take the time to make your own watercooling, also take the time to make sure its engineered right.

Re:Personal Experience (2, Insightful)

quantax (12175) | more than 12 years ago | (#3317114)

Oh yea, I forgot to mention, skimping on these sort of things for money is dumb because by using jury-rigged methods such as this, you usually end up spending MUCH more in hardware replacement costs. All it takes is a couple drops and could easily blow every component attached to the mobo (which is pretty much everything). Watercooling is not the sort of thing you cheap-out on since the consequences can rack up in cost pretty quick.

my friend had me mill one for him for a science experiment. actually , ended up about 5 of them. he bought 2x2x1" aluminum blocks. i milled two holes through (one end to the other), side by side. he tapped them, and attached plumbing devices to the newly threaded areas. The other method was to bore four holes - two holes one one side that went 80% through, and 2 holes on the adjacent side that also went 80% through. tapped, and attached appropriate connectors. no leaks to patch. since the tops were flat, he also took the old heat sink + fan, removed the fan, and used that to dissipate evem more heat.

i never got the results back, but if anyone's interested, i can get the data to you, along with pics and more details.

medscaper (238068) | more than 12 years ago | (#3317212)

This seems like absolute junk to me. No offense, but any CPU or box you hook this up to would be toast in minutes. I know, I toasted one with this same technique a few months ago looking for a cheap solution.

The problems with this system are numerous.

1. The pump will only work for 10 minutes at a time. Great if you power up once a day to check email and then power down again.

2. The surface of the cooling block is absurd. If you don't have good contact, you're out of luck.

3. The cotton thread will stretch and contract, and eventually the "double knot" will break or become worthless. Savage an old CPU fan connection bracket if you must, but don't do THIS. Please.

4. The leaks would be horrendous and fast. The rubberbands are susceptible to the heat of the block, and will break immediately.

I'm not trying to be a jerk. I did try this unsuccessfully a few months ago, and then sucked it up and shelled out $90 at Fry's for some moderately good quality parts - a block, some real pipe fittings, and a good eHeim pump. It's been running 24-7 for some months now, with absolute perfection. It's quiet, fast, and the tests I run (every month) when I shut down the pump just to see what would happen, result in a nice, quick shutdown upon CPU core overheat (takes about 5 minutes). Distilled, clean water thrown on a running motherboard had no effect, so I've used that. No oil, no antifreeze, no water wetter. It's all worked out great.

Just shell out the $90 or $100, spend some time, and do it right.

trelaneopn (563678) | more than 12 years ago | (#3317248)

I own a manufactured liquid cooled case. The performance is excellent and at 350 wtih powersupply, was really fairly reasonable. If you're interested in liquid cooling the case has performed in a superb manner. (keeping the 2000+ sitting it it at around 120f. When I get the new 200w cooling unit I expect it to drop even lower, as the fluid temp is still only 10f above room temp.

In answer to the obvious question, no I'm not planning on overclocking, because unlocking the palamino clock is too much trouble. for those interested in the case I purchased it can be found at Koolance [] I got the 602 which is a modded antec case, that antec claims is a soho fileserver case.

This "31337 m0d" runs for approximately 10 minutes before the pump overheats. That's really useful if you're only interested in watching your boot sequence.

And anyway, all watercooling systems are DIY mods. That's the whole fucking point. This was truly a waste of time and bandwidth.
