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.

This board has the following...

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.
