Hey,
Noise will be no Problem, due when Time has come ill build up tha Rack in a "real Serverroom" in the basement.
It will be air-conditioned and every Server will has its own fuse.
Due we have a "Dachs" http://www.senertec.de/derdachs.html (Block Heating Power Plant) in Island Operational Mode in the basement,
which means, it can run without any Power Needed to start, i dont need any USV's.
Well, and with the power consumption, well see, maybe we will be a industiral Consumer someday.
