m50d's Journal: Looking to set things up

What I have:
Computers:
1 modern x86 machine (Semperon 2600+). PCI only, and sound is so modern it has no DOS support. Onboard sound, also a PCI sound card (both no DOS support), and 10/100 (possibly gigabit) ethernet. Standard parallel and 9-pin serial ports.
1 pentium 1. PCI and ISA, onboard sound which presumably works with DOS, IIRC onboard ethernet (haven't tested the speed). Standard parallel and 9-pin serial ports.
1 486. ISA only. No sound. Standard parallel and 9-pin serial ports.
1 Sparcstation 10. SBUS only. Sound, onboard 10baseT/AUI ethernet. 25-pin serial port and sun parallel port.
Networking equipment:
2 PCI 10/100 ethernet cards.
1 ISA 10baseT/thinnet/AUI ethernet card
4 cat5[e] cables
2 24-port 10/100 hubs, rear stacking connectors, AUI, one with fiber.
1 8-port 100baseT switch.
1 plip cable
1 25-pin slip cable
1 25-9 pin serial adapter
What I can probably accquire:
1 ISA 10/100 ethernet card
1 cat5[e] cable
What I can connect to:
LAN. 1 ethernet jack. Must have a single MAC address on the end of it.
What I want:
Play modern windows games over the LAN with IPX
Play dos games with sound
Permanently accessible webserver running
All computers able to access the lan, at least with TCP/IP
Anyone figure out a way to get this all working?
TIA for any advice
