http://imgur.com/a/8urBpI moved my miners out to the garage yesterday because without central air the AC wasn't able to keep the basement cool. With folding I keep my farm inside and shutdown in the summer because of electricity cost but since mining covers the electricity, I needed a new location. I had to pull 30m of Cat5 underground through some conduit that had been thoughtfully pre-installed and then re-terminate it to get an internet connection out there. It's a detached and un-insulated grage/storage/work space so I ended up hanging my boxen from the ceiling on shelves. I put a switch up there and a power bar and use VNC to keep an eye on them. It's nice having them out of the way but it is pretty hot up there so I had to twist tie four 2000+rpm 120mm fans around each GPU stack. I can put a 120mm fan pulling directly out of the cards exhausts because I don't use dummy plugs and instead VNC in and tell windows to pretend there is a monitor on each cards VGA output. The cards still hit 80C with the fans at 70% because the air temp is 35C+ at that height and with no air circulation in the building. I think I will add a small box fan to get some air from near the floor up to them. There are two towers, one is a striped down Lian Li PC-A05 and the other is a small Antec mid tower. Each has 3 GPU's all squished together on old high-end EVGA motherboards left over from folding. The short Lian Li has two 5830's with a 6850 sandwiched in between on a Thermaltake 750W PSU. The Antec tower has an unlocked 6950, a 5850 and a 5830 from top to bottom on a crappy Nexus 1100W gold unit. Altogether it is about 1.7Ghash and probably works out to a bit over a kilowatt. I might purpose build a 4x5770 rig now I have the heat taken care of and I'm off school for the summer but I have to check over if it's even feasible with the price staying under $20.
