That seems pretty darn simple to put together! :Q
A few motherboards/CPUs, and a hub/switch, and place a few big long sticks through some of the ATX mounting holes, with something a bit bigger over the top of the sticks to put a gap between them!
Then all you need is a neat way of stacking the PSUs and attaching some form of tiny HDD or ZIP drive (i can get 250MB hdds from my college for £1 each....if you're interested in a setup like this anyone, anywhere, i'll go grab a few more

- each one is fine for a minimal install of 98 and Seti

)
Now if only i had £2000.....anyone wanna help out for the TeAm!?
