I believe many of you are following the ROCKMINER thread, but just in case: They just released the specifications for their first product. Sales seem to be starting shortly/now(!?) as well. When considering the power consumption, keep in mind this is a nominal consumption and it includes the whole miner hardware and fan. Furthermore it only features 4 chips, so the whole overhead may again be significantly less when it comes to large scale mining boards. Gen 3 hardware is beginning to ship! Awesome, huh?

Just saw that and ran some quick numbers. Payback is questionable even with 25% difficulty increase per month and cheap power...

Let's hope that the overhead is cheaper for larger miners.

40W is in the range of solar panels and batteries if you really want to go green
