Do you have power supplies that would power the S3's?

Are the S1's the entire unit or only the controller and boards?

how many GH/S per board on the ''''17 - Black Arrow Bitfury Boards $10$5 each''''' ?

PM sent. 

1TH from 6 S1 units - thats about 1400W correct?

The S1 units can go to around 1w/gh at a lower voltage, but still it wont do much to make them profitable. At $0.15/kwh assembling my 5 units into a stack was simply to save space and run it on 2 fans only. Ive got a box of powerful fans and big aluminum hunks to deal with still though - Im hoping each frame is worth >$5 to a scrap dealer, and the fans are worth about $10 each to myself whenever ueful for other hardware (I changed all the rockminer fans for antminer fans)

edit: a bit of gooling indicates that scrap aluminum from radiators or cast aluminum is worth less than high-quality items like car rims - about $0.50-0.70 per pound.

any updates on the returns?

I haven't yet gotten out a wattmeter, but I have 4 units stable at resistance of 2.05-2.15 kOhm, or about 0.74-0.77V. 193-212 MHz gives 93-112GH per unit

Yes i definitely did. I will start a new thread for psus later

Since you are NOT Bitmain, I'll assume you are ignorant of Bitmain's ethos.
Firstly, no one asked to be given free boards, just sell the boards free of the heatsinks that undoubtedly add extra weight and thus to the shipping cost (which Bitmain do not make a profit on).

Secondly, Bitmain have said repeatedly that they are here to support the bitcoin ecosystem and that is very well espoused by their initial pricing without added shipping costs. Additionally, they have designed and marketed miners (S1 and S3) that fit within the small miner's pocket, but the current shipping is proving to be prohibitive to the nascent miner (me included!).

Finally, I doubt very much that another company can sell their miners with Bitmain boards cheaper than Bitmain, but even though they did, it would simply mean that Bitmain shift more boards (loaded with their set margins) with less overhead costs; and that can not be a bad thing for themselves or their stated aim to support the bitcoin ecosystem.
