Re: The Habanero - 650GH/s - Batch 2 Shipping June 9th, $850 ($1.3/GH/s)
Well I spent a good bit of time breaking the rules and testing higher voltages / clockrates and cooling configurations. I am by no means suggesting that anyone attempt to replicate! I seem to get the best performance with the following settings...
Voltage: .995V
Clockrate: 975Mhz
Temps: 94-99
Hashrate: 750 GH/s +/-
Kill-a-watt: 1157
About 60 watts are from some ridiculously powerful fans that I swapped out with the stock fans on a CoolerMaster 240L. I started this machine around 5AM CST and it was running at 750 until this afternoon when it dropped a little. Perhaps that was due to increased ambient temps which were lower overnight, and are in the mid to upper 70s right now. I just took these screen shots a few minutes ago.
More tweaking to come, but pretty optimistic so far.

PICS!!!!
Breakdown of parts, price and where to get them? Also you mentioned a case etc in another post... let us see what you got... I am curious on just how much it would cost to part your setup out including PSU and rPi.
1. Cooler Master 240L
2. Original fans replaced with 2 Delta 1212GHE-CF00 | 240 CFM | Max Air Pressure 27.48 mm H20
Fans are pulling (as opposed to pushing airflow) so that they blow the hell out of the back of the board. They are a bit expensive, loud, and at 29.4 watts they are not ideal. I just wanted to see what performance was like with these.
3. PSU for testing is just a Thermaltake 850W
4. Controller is an Intel NUC running Ubuntu
5. This one is not in a case. As you can see in the picture it's just sitting on my desk so I can test it.
We do have some interesting solutions in the works that I will post soon. Feel free to PM if you have any other questions.
