Just got my D0 and R2E before the weekend, and it's looking good so far :>
Running a bit hot, even at the low voltages. I reached the point where I'd have to up the voltage a bit if I wanted another 100mhz, but it's gonna have to wait for my new case and water cooling.

Its running on a Cogage True Spirit and the ram is untweaked on that screenie. Its G.Skill 16000 Tridents, currently going at 1532 1.5v 7-7-7-24.
