I know this type of project is right up your alley and you've already pulled the trigger so to speak but you seem to be the perfect candidate for having your S7s hosted in a data center. Good luck and I hope it all works out for you so you can get all of your machines pointed towards Kano!
Yes, I'm pulling the trigger. I'm just the type of guy who prefers to do it themselves. If anything were to go wrong with a rig, there is no one to blame buy myself or the manufacturer [Depending on what went wrong]. I feel better not being concerned about if anything went wrong, would I be compensated for the loss of a rig(s). I've seen too many horror stories for me to risk 78 or more rigs potentially getting lost, stolen, burned up, etc... then hope they had insurance that would take care of it IN AN EFFICIENT AND TIMELY MANNER.
There are good hosting centers I might consider trusting in the future, such as, Toomin, sidehack, or Oregon Miners. That's about it. In the mean time, I intend to keep going here till I reach 600 amp demand and cannot add anymore. THEN, I will see about hosting the rest afterwards. The price savings between keeping them for myself verses hosting is very little difference IMHO. At least during the winter. At present, my revenue is 4 times my power costs.
EDIT: BY THE WAY, Good job finding that block on
kano.is
That was WAY TO MUCH MONEY to loose to replace them. So, Bitmain is still on the Good List for customer service. 
Although I would want the fans running flat out for that...
