I just (5min ago) got 3 brand new S1 and EVGA1300 to run them, but cannot employ due to "family" objections about noise, cords, etc.
If anybody is interested, send me PM, I am in Houston. 
You could undervolt and put them in something like this ---silent---

Or with that power supply you could run two more undervolted/underclocked to 153gh and almost silent
