Regarding power it has 4 connectors three under the yellow tags, had to get pcie to atx converter cables to power the thing up or it trips the overcurrent on the Hx1000 psu
32GB was the easy way to get quad channel per cpu and if i ever run einstein on it that uses about 250mb per instance
Cpu's are opteron 6176se 12 core at 2.3ghz thats 48 cores of folding goodness, on the current workunit ( 6900 bigadv ) thats 09.03 frame time and 224500ppd according to HFM.
Mr Biffa may know better but its the fastest ive seen on bigadv
I realy hope Bulldozer turns out to be kickass as the 16 core opteron version should drop into this with only a bios upgrade
