The beast is out of the picture but to answer a previous question it's housed in a Cooler Master CMStacker. That doesn't actually fit our Dual Xeon Supermicro motherboard though so some DIY was needed.

Two of my computers next to each other, both (naturally, since all of mine do) running Linux (Though not exclusively.. there's some Minix, NetBSD, Bluebottle, Atari and so forth).
