We are quite a fan of Noise Control's products so far here at OcPrices, with both their Magic Fleece noise dampening material and Silverado coolers providing great quiet solutions for today's noisy PCs. Their latest product is the "Stealth Tower" case, complete with "whisper box". The Stealth Tower is basically a high-quality tower case pre-lined professionally with magic fleece. In our tests of the magic fleece, whilst the drop in noise was quite significant, the majority of the noise was now coming out of the back of the PC, via the case fans and PSU. Naturally these couldn't be lined with the fleece! With the stealth tower, Noise Control have constructed a "whisper box", a metal box heavily lined with fleece, with some cleverly aligned holes that allow air to circulate, but should stop 90% of the noise from escaping.
As you can see the case is quite a behemoth! With five external 5¼" bays and four 3½" bays, you won't be running out of space any time soon. Because of the case's heavy fleece lining, and the fact that it is a big case already, the stealth tower is a heavy object. Hauling it onto some scales revealed an empty weight of 12.5kg (27.5lb).
Thanks to Chillblast for providing me with a World Exclusive review on this case. You can *only* buy this case from them if you are in the UK since they are the only Noise Control UK distributors. The case costs 166.99 inc. VAT - but as you are about to see, you certainly get your money's worth. Lets take a look at some mug shots.

Case Exterior
The stealth tower is an attractive case despite its bulk, with a sliding cover to hide CD-ROM drives and other paraphernalia from sight. I was particularly impressed with the whisper box, which blends seamlessly with the case's design.
Now that we have taken a look at the exterior, lets have a look at the much more important interior where the Stealth Tower really comes into its own compared to other cases.
Page 3:
The Interior
Inside the Stealth Tower you will find wall-to-wall carpeting the likes of which you have never seen! Most of the panels are double lined with the noise dampening material, so the dampening effect should be much more profound than when I tested the Magic Fleece kit myself.
The large metal expanse with no fleece attached is where you install the motherboard and other components. Behind this tray is a double lined side panel
You can see the notch in the second layer has been carefully cut so that the side panel fits on snugly, fitting the case skeleton like a glove.
You can see that the drive bays, where normally a lot of noise escapes is extremely heavily lined with fleece. I am very impressed with the sheer amount of noise dampening matting used in the case - if you were to DIY a case of this size with the same extent of sound proofing, you would have to factor in at least two fleece packs - which would set you back over £80 alone from Chillblast.
Here is the inside-back. Plenty of spare PCI slot gaps, and space for an 80mm fan to be mounted. This is where 90% of the noise escapes in a regular fleeced case. Enter the whisper box!
Page 4:
Whisper Box
The whisper box is large and heavy contraption that attaches onto the back of the Stealth Tower by means of extremely strong magnetic strips.
Once attached to the case, it has no likeliness of coming loose without a good tug, allowing you to drag the case around without it slipping off. If you are planning to carry the case around however, of course it is a good idea to remove the box.
The whisper box works on the premise that hot air can move by convection, whereas sound travels in straight lines. The box is split into two sections, one for the PSU, and another for the case fan / PCI peripherals. Nearly all of the sound waves are deflected straight into fleece, where as the warm air coming out of the PSU and case fans can drift up to the top of the box and be expelled, and warm air from the case fan is expelled from the bottom due to pressure build up.
The entire interior of the whisper box is heavily lined with magic fleece noise killer, and thus weighs quite a lot. It's build quality is fabulous, and it looks like part of the case rather than just a third party add-on.

Performance
I will compare the Stealth Tower to my other case, the Lian Li PC-60. I have fitted both with the same 80mm case fan and the same Enermax 430W whisper PSU. Lets compare both decibel readings, taken with the following contraption, and then case temperatures.
For the CPU I have fitted a 2100XP processor, with an Arkua copper core thermoengine. Its not the loudest of coolers, but certainly couldn't be considered quiet either. It is about on a par with most "regular" 4500rpm fans. The graphics card is the Creative GeForce 4 Ti-4600, which has quite a loud and annoying fan - and definately the noisiest component in my PC. It will be interesting to see how the Stealth Tower copes with it.
Case CPU temperature (full load) Case temperature
Lian Li PC-60 48.9 26.4
Stealth Tower 52.1 29.0
The Noise Control case results in a 3 degree increase on both the CPU and ambient case temperature. Initially I did the test with no case fans installed in any case, and the difference was a much more profound 6 degrees. The CPU was also a rather worrying 51 degrees with the Lian Li, and a borderline pass of 57 degrees with the noise control case. It just goes to show how stupidly hot these Athlons are getting now - even with a good cooler. Lets see whether the reduction in noise is worth the temperature cost. I also dug out my old fleeced case that I built myself and fitted the same components again. Readings were taken exactly half a foot from the front, then the side and then the back of the case about half way up in all tests.
Case Side Back Front
Lian Li PC-60 48.0 Db 56.9 Db 50.8
DIY Fleece case 43.5 Db 55.4 Db 44.5.1Db
Stealth Tower 40.1 Db 45.3 Db 40.1Db
The extent to which the Stealth Tower reduces system noise is truly amazing. There was barely an audible whisper coming from the whole PC, and it certianly showed up my l33t fleecing skills or lack thereof! To be fair to myself, the main difference between my DIY effort and the Stealth Tower is the whisper box on the back, it really does do wonders for noise reduction, with the PSU only audible if you put your ear to the whisper boxes top port. The differences in Db may not look like much, but when you consider it is a logarithmic scale, the differences are really VERY significant. Just for fun I placed a Delta screamer in the Lian Li (not actually connected to anything except the fan header) and then again in the fleece case and listened for the difference. I would say that the difference was maybe 80%. In the Lian Li, the Delta is as-ever, unusable in my opinion. In the Noise Control case it really isn't so bad! Finally! That said, I find it unlikely that anyone investing in the Stealth Tower would then negate its huge potential by putting such an uncivilised cooler in it!

Conclusion
The Noise Control Stealth Tower case is big, beautifully made and sublimely quiet. Sure you get an increase in system temperature compared to an aluminium case, but the differences in volume need to be heard to be believed. Remember this review was conducted using regular equipment, with the likes of Zalman CPU coolers and PSU's, a silent PC - even an Athlon 2100XP PC - is now a possibility. People hankering after tranquillity, and especially those that NEED quiet PCs, for audio visual work or recording etc should not hesitate to buy this case. I am a total sound Nazi, and although I found the original magic fleece DIY kit impressive, the amount of noise coming out of the back of the case was still an annoyance. With the Stealth Tower, Noise Control have finally come up with a viable solution, and for that I humbly thank them!!

Noise can be good sometimes. (Score:2, Interesting)
I've found the noise from the Athlon 1800+ in my bedroom to be quite soothing in the amount of white noise it creates in the background.
I did a little somewhat unscientific case study on the white noise it generated a few months back. I started shutting the box down at night while I was in bed. It turned out after 1 week of shutting it down to get rid of the noise that I actually had a harder time getting to sleep, and often woke up in the middle of the night. Within a few nights of leaving it on all night and day again I was back to sleeping like a baby.
With a baby on the way I'm tempted to set up a computer in the baby's room, not only so I have something to do at 4AM in the morning between feeding/changing, but also as an introduction of white noise into the room. I guess I'll see how well this works, maybe it'll be as soothing his mother's voice.

A perfectly quiet room is not conducive to a good night's sleep - you wind up being woken by small noises, such as the house creaking, wind blowing through trees, the HVAC system coming on and turning off, etc. White noise gives a higher base noise level that makes these events less noticeable because they're not such an abrupt change from what's in the room otherwise.

White noise can help muffle the ambient noises that disturb the sleep of many urban dwellers (like sirens, cars, fighting neighbors, amorous neighbors, etc.) Without white noise, theres' silence broken by sudden sounds; with white noise, there's a more steady low level of noise and the sudden sounds are less disturbing.

The infants were unloaded.
"Now turn them so that they can see the flowers and books."
Turned, the babies at once fell silent, then began to crawl towards those clusters of sleek colours, those shapes so gay and brilliant on the white pages. As they approached, the sun came out of a momentary eclipse behind a cloud. The roses flamed up as though with a sudden passion from within; a new and profound sigruficance seemed to suffuse the shining pages of the books. From the ranks of the crawling babies came little squeals of excitement, gurgles and twitterings of pleasure.
The Director rubbed his hands. "Excellent!" he said. "It might almost have been done on purpose."
The swiftest crawlers were already at their goal. Small hands reached out uncertainly, touched, grasped, unpetaling the transfigured roses, crumpling the illuminated pages of the books. The Director waited until all were happily busy. Then, "Watch carefully," he said. And, lifting his hand, he gave the signal.
The Head Nurse, who was standing by a switchboard at the other end of the room, pressed down a little lever.
There was a violent explosion. Shriller and ever shriller, a siren shrieked. Alarm bells maddeningly sounded.
The children started, screamed; their faces were distorted with terror.
"And now," the Director shouted (for the noise was deafening), "now we proceed to rub in the lesson with a mild electric shock."
He waved his hand again, and the Head Nurse pressed a second lever. The screaming of the babies suddenly changed its tone. There was something desperate, almost insane, about the sharp spasmodic yelps to which they now gave utterance. Their little bodies twitched and stiffened; their limbs moved jerkily as if to the tug of unseen wires.
"We can electrify that whole strip of floor," bawled the Director in explanation. "But that's enough," he signalled to the nurse.
The explosions ceased, the bells stopped ringing, the shriek of the siren died down from tone to tone into silence. The stiffly twitching bodies relaxed, and what had become the sob and yelp of infant maniacs broadened out once more into a normal howl of ordinary terror.
"Offer them the flowers and the books again."
The nurses obeyed; but at the approach of the roses, at the mere sight of those gaily-coloured images of pussy and cock-a-doodle-doo and baa-baa black sheep, the infants shrank away in horror, the volume of their howling suddenly increased.
"Observe," said the Director triumphantly, "observe."

I'm currently gathering pieces for a passive watercooled setup (no fans) that handles cooling the video, system chip and processor. The power supply fan will be removed and replaced with a low-voltage 120mm top-mounted fan that runs silently with good airflow (for HD cooling as well).
Rather than mount the radiator inside the case, the radiator will be top mounted with a custom lexan mount. This moves the heat outside the system (closed box). In addition, the inside will be sound deadened with leftover Dynamat Extreme [dynamat.com] from my car stereo install. This should result in a cool looking, silent machine, with no compromises.

3. Replace case fans and possibly power supply fan with Vantec Stealth fans.
4. Avoid slot loading DVD drives (i.e. like car cd players, no tray) because noise gets out of the slot.

Very true. I think it all boils down to personal preference. Some people feel happy with certain levels of noise while others would want it to be quieter.
In my experience, hard drives have never bothered me. Only when I upgraded to an athlon xp did the CPU fan start to drive me nuts so I started investigating alternate low-noise cooling options. I am willing to trade the higher noise of a 7200 rpm drive for increased performance, but with it comes to CPUs the cost is IMHO too high unless you get specialised cooling gear.

There's a bunch of quieting gear on Quiet PC [quietpcusa.com], including HD case enclosures. I'd really like to know how well their fan-less CPU and GPU coolers work.
You're very right about HD's though -- my older PC had 3 7200 rpm SCSI drives in it. I finally cannabalized it, removing the SCSI drives and replacing them with a single IDE drive (with twice the capacity). It's much quieter and much faster now (yes, they were old SCSI drives).
If you have a Maxtor drive you can download a utility that will put the drive into "quiet" mode. It reduces performance somewhat by slowing down and re-optimizing seeks to reduce head movement. Did this for the 80 GB drive I put in my TiVo.
Seagate drives are currently considered the "quietest" though, so take that into consideration if buying a new drive. I believe they're even quieter than the Maxtor liquid bearing drives.

I tried Seagate, Maxtor, and IBM drives when putting together my quiet PC. The Seagates are the quietest, but they're not really quiet (even in a Molex SilentDrive enclosure, which helps significantly). I've wound up putting a lot of effort into building a ramdisk root partition and doing heavy readahead into RAM so that the hard drive is almost always spun down.
Really, the Seagate's seeks are extremely quiet but the standard hard drive spin noise isn't that much more quiet than the others.

I'm also using a Barracuda IV 80 gig. The rest of the machine is virtually silent, using a Siemens mobo that keeps the cooling fans off unless the heat rises (Golden Orb heat sinks keep the CPU fan off pretty much all the time, a custom low-heat convected power supply likewise keeps the power supply fan off) and it has a fanless video card. The room has no other noise sources in it and is fairly well insulated acoustically. While the Barracuda is quieter than the IBM drive by a long shot, it's not that much quieter than the Maxtor except for seeks where the Seagate wins out handily.
It's all relative, in a typical home environment the Barracuda IV would be great. In my environment I throw it in a molex SilentDrive enclosure and have a Stealth Armsystems acoustically shielded case for the computer, and I still try to keep it spun down as much as possible--it's far and away the loudest piece of the system. The SilentDrive enclosure kills almost all seek noise but isn't as effective at cutting down the spin noise (it does help some). You really need to keep the room cool if you're going to put an 80GB drive in a SilentDrive, but I do that anyway to keep the other fans off.

It is. I have one and it is VERY quiet. "2. The MCX462 doesn't mount on a P4. An Alpha 8045 costs less, and performs better [anandtech.com]. Instead of a Vantec Stealth fan, a low rpm sleeve-bearing fan (Panaflo, Papst, etc) running at a reduced voltage of 5V or 7V (by simply rearranging its power wires) will be considerbly more quiet, and typically provide more than adequate airflow. Panaflo's can commonly be picked up for $3-5. "
In that case you can get an MCX423 or 478. They are the same heatsink with different mounting apparatus for P4 socket 423 and 478. I do know the Alpha costs less and it has the nice 'hole mounting' feature. If it performs better as well then I stand corrected. I was not aware of that.
"4. I assume you mean when a disc is actually spinning in it? The Pioneer slot load drives are quieter than a lot of other tray load drives. "
I have such a drive (16X/106s) right now and I was meaning that the noise from inside the machine (fans) gets out of the slot. The disc spinning makes noticeable noise too. It is definitely noisier than my 40x12x40 Plexwriter.
"3. You shouldn't need a case fan. Replace your PSU fan with a voltage-modded sleeve bearing fan."
When in doubt, add a fan :-) The rear case fan on my machine is right near the CPU so this given additional airflow over the heatsink which is always good.
"6. Rounded cables providing better airflow is a bunch of BS. What they will do is cause drive instability. They're designed flat for a reason."
I have since been enlightened on that one and I agree with you about rounded cables not having better thermal characteristics. I use rounded cables because the physical configuration of devices I want simply can't be done with flat cables because they obstruct one another.
"Motherboard chipset fans should be avoided, and often can be safely removed. Video card chipset fans should also be avoided (GeForce4 MX440s are available fanless), but for performance cards, are sometimes inevitable."
On that one I prefer to use what the manufacturer recommends. If the chipset comes with a fan, then use it. It's there for a reason.
"Typically, the loudest thing left in your computer will be your hard drive. Seagate Barracuda IVs seem to be the best choice here."
Hehe not in my machine ... the CPU fan is noisier than everything else combined. Honestly my comfort level for noise allows noisier HDDs than the seagate, although I do agree that those are excellent drives.

The original Apple ][, ][+, ][e were convection-cooled and silent. I was used to PDP-11's and such and when I saw my first Apple, I said, "Wow, they must have brilliant thermal engineering." Turned out they had NO thermal engineering. If you put expansion cards in it, it would overheat.
The original 1984 Macintosh was silent, and I loved it. There were no expansion cards, so no expansion card issues. I'm not sure whether the issues related to overheating or not, but there were a LOT of issues relating to the power supply on those early Macs and I'm inclined to think thermal design MAY have been part of the problem.
It's too bad other issues with the Cube (pricing, mostly) may have discredited it. I bought a standard-style G4 instead of a Cube at the time, figuring that, as with laptops, a design with lots of components crammed into a tiny space might be less dependable and more defect-prone than the spacious G4 tower.
But I really miss the silent (not just low-noise) operation of the 1984 Mac and Mac Plus. (All the Apple ]['s I ever worked with had aftermarket fans on them...)

No hard drive. I have heard that Steve Jobs was very firm about not making a Mac with a hard drive; he felt it was more important that the Mac be silent than to have the storage of a hard drive.

I'm sure you are correct. I remember seeing an aftermarket mod for the Mac, which added a cooling fan at the top of the Mac to suck hot air out. The ads claimed that your Mac would be much more reliable with the active cooling.

Why doesn't someone put a simple anti-noise circuit, a microphone and a speaker on the output of the PSU? It would not restrict airflow if cleverly placed and the sound is consistent enough to easily generate the anti-noise.

Active noise cancellation? (Score:2)
I am guessing that if someone researched this carefully, they'd find a handful of frequencies that contribute the most to fan noise, and a small electronic device could be designed to counter just those major harmonics in the fan noise.
Or I could be talking out my ass, who knows?
Re:Active noise cancellation? (Score:2)
Easy to try out - pick up a pair of noise cancelling headphones (Bose used to make them, I think Sony do too now) and sit near the case. If it works, rip them apart and run the output into a loudspeaker. The problem would probably be balancing the output to have the same frequency content as the source noise.

White Noise Generators (Score:2, Interesting)
A recent advancement in technology that is becoming widely used in psychological counseling and health service settings is the random noise generator. These devices, similar to the size and configuration of a smoke detector and/or an air purification device, emit a wide frequency band described as "white" or "pink noise." Adjusted to a relatively low level, these can be effectively utilized in the spaces in which the client interaction occurs to mask undesirable environmental sounds without negatively impacting the client interactions by being intrusive in nature.
AFAIK the noise from a fan is pretty close to white.
Seems that in medicine though there are always conflicting studies so I expect to be presented with the opposite result in a case study.

Redesign the Case First, then the Cooling System (Score:2)
Apple has done quite well with their iMac designs. And the Cube was an interesting, if not entirely successful, attempt at a tower-ish design that didn't require a lot of heavy cooling equipment.
Sure, they're not that upgradeable, and you can't cram 3 video cards, 6 SCSI controllers, 4 sound cards, and a dozen hard drives, but if you need to do that, sound isn't your first consideration anyway. And if it is, try a disk array and remote terminals; put the noisy bits somewhere else.
Air flow is the key. Convection can be a great help, but towers aren't designed to allow that to work efficiently. Volkswagen made an entire car without a radiator or any kind of water cooling system, primarily due to re-examining the design of the car itself. Surely there are better case designs to be had.

1.) Large, low-rpm fans - cut holes, use adapters if necessary. Nothing smaller than 80mm. That means replacing any chipset / video cooler fans too. Nothing higher than 2500rpm--preferably around 2000. Use manually adj. speed fans if possible so you can achieve proper airflow around hotspots and balance case intake / exhaust.
2.) Don't overclock excessively. If you need extra cooling as a result, it's not worth it.
3.) Quiet hard drive(s). High frequency sounds are much more annoying, so if you go with a 7200+ rpm drive, buy a really quiet one like Seagate's Barracuda IV ATA or else sandwich the drive in aluminum and acoustic foam.
Sure, there are more drastic measures. But these
