ok, first of all, the good news is we cut our heating costs to 0. If you need your room heated up, just open a door and wait 5 minutes.
Then, this is our Rig that we built this weekend:











We built everything from scratch, and made our shelf modular, so new GPUs can simply be stacked on the top layer(or better the second layer from the top, and move switching, bitcoind and upstream up by one). We can do a total of about 3.3 GH/s with this.
Setup from top to bottom:
top layer: 1x iEi Atom SoC with a 1.6Ghz dual-core(+HT = 4 cores) processor and 4 gig ram. this machine connects to the internet, provides NAT and DNs. It also hosts propool(my self written backend), bitcoind and namecoind for merged mining. The DNS server automatically changes the entries for the pool host in case its local pool fails at some point, so the rig will never go down. In front of it, we have a modded linksys router that currently acts as a switch to provide all the miners with network access and allows for one maintenance access.
second layer:
My 1.3 GH rig, Celeron, 8gig DDR3 ram(didnt have smaller ram modules), running debian Squeeze, with:
1x 6770(the "flying" one) @ 250MH/s
1x 6850 @ 240MH/s
1x 6950 shaders unlocked + overclocked @ 370MH/s
1x 5850 @ 360MH/s
third layer:
rig of a friend, with some cheap sempron, a weird ubuntu that is to be replaced soon since starting miners is a bit uncomfy,
2x 6950
1x 5850
1x 5650
fourth layer:
The magic mystery mining carton. I really dont know whats inside, but its output is about 750 to 800MH/s. I know that there's 2 cards inside, and they keep "cool" at about 80° C.
Oh, there's some more pics at

PLEASE EDIT YOUR POST and scale the pics down to a managable level.
