We're working on another deal that we're trying to get to ship today. This time ~10.2(TH/s) which hashes at =<11.2kW for a total price all in for everything < $10.6k. So a little bit cheaper on the (GH/s)/$ than the most recent purchase. We are working with these -

https://bitcointalk.org/index.php?topic=680423.0 If we complete this move then this will take us up to 27.7(TH/s)@29.3kW of which we currently need to pay a flat rate hosting cost of $0.14USD per kWh. So this would mean that we're now getting 22.6(TH/s) for roughly the price of 9(TH/s) of Neptune refunds that we would have received those units about three weeks ago at the earliest. While the last network difficulty change was 3.08% and the next one due later today is expected to be =<8%. So if you adjust the 9(TH/s) loss by those two difficutly changes than that'd be roughly the same as 10.01(TH/s) needed to compensate. While the Neptune's are 25% more power efficient than our rigs we are getting over 125% more relative hashrate. Adjusted for the difficulty changes since we'd have theoretically possibly received the Neptune's. While this move would leave
BTC87.56 in the wallet for future moves. Although we still have a $25.7k commitment to AlphaT for their currently quoted 1(GH/s) of Scrypt ASIC's. We feel that if they don't upgrade that hashrate or unless the BTC price starts to rise dramatically. Then we may possibly renegade on that current deal in doing so losing our
BTC12.00 30% deposit in the process. We'd currently have to pay them another
BTC42.71 if we feel we can at least easily ROI on that then we'll go through with it. On a brighter note AlphaT should have an official update on shipping today. So if they can offer us a big enough carrot then we'd go through with the final payment.
