Nice setup! Out of curiosity, what's a standard rate for your colo? The lowest rate I found is $135/m/device but they want a year-long contract. That's no beuno...
Have you found anywhere that will do it for $ 135 per month that is accepting new miners? I been having an issue finding a colo that is open (and looks reputable).
As for power. My calculations are that a miner will cost (at 10 cents per KWH), around $ 100 per month in electricity. I know everyone can get electric at 6 cents per KwH, check your bill. Delivery fees, admin fees, and your "out the door costs" are likely at 10 cents per KwH.
So if my electricity costs $ 100 per month, I think if I could find someone to deal with all the noise, cooling, etc, for $ 35.00 per unit, I would do it..

Remember, difficulty goes up all the time, each week my miners make slightly less bitcoin than the last week. That trend will continue.
