bobsag3 has the right idea really, build your own, forget about all that raised floor, hot/cold aisles, 47U APC racks, redundant diesel generators etc etc. This bitcoin stuff is short term. You just need a well ventilated warehouse with decent aircon and flow. Get industrial shelving to put the miners on and make sure you have enough electricity to keep it going.
Exactly. You not only don't need uninterruptible power, you'll be better of buying cheap, explicitly interruptible power from the utility company using special industrial/agricultural/pumping tariffs. I even dare to say that air-conditioning is an overkill, good airflow (which for SP10 means getting rid of the cases) and maybe cheap, evaporative cooling will be good enough. Get a small UPS to have a continuous network connection just for the local switches/routers and security cameras.
Or just admit to yourself that you've got your Bitcoin mining hardware as a status symbol.
