5 antminer S1 units, cooled by a pair of Cougar 90cfm fans and running approx 460GH/430W  (still working on tuning, 2 units are only running 70GH). Runs off a single CS650M

ps: temps are up around 60-65C, and the hardware seems fine with that. I plan to get it in a cooler location soon though to drop temps 5-10C
