Taken a year, it's still not quite finished, but here is my retro setup.

I had something very similar in the UK but as anyone with more then 2 computers can confirm. cabling becomes a nightmare. so have put more thought into it this time.
This is my "THE RACK OF POWER" (consumption)

Recent find 386 in tower with 286 badge. Future project.
On the floor I have a massive tower case which original had the P2B-DS motherboard but is currently empty.
Above that the S478, GF 6800 Ultra Win9x/XP build: P4P800 End of Win98 Support Build
On top is my Quad GTX590 WinXP/Win7 build: My main XP rig. LGA 775 Asus P5N-D, GTX590 SLI, SB X-Fi

Desk has 3 HP EliteDisplay 201's chosen for having VGA/DVI/DP inputs and a Dell 5:4 monitor. All 4 VGA inputs connected to a separate KVM.
DVI is often used as a 2nd screen on more modern computers.
DP used to be used for laptops but these need setting up again.
Also on the desk is my SC-55 (typically hooked up to the Osborne) and my Logitech Z5500 speakers.
To connect this many computers to the speakers I have a 4 port toslink switch, or each PC also has a standard audio cable from the back I can plug the speakers direct into.
This does means I loose true 5.1 surround sound but currently with 2 small children I'm actually using my headphones more at the moment.
The cabinets above the screens have all my CD's and above them some of my Big Box software. (I think the rest is still at my parents)
