poizin Also, is this worth it? Would all I need to do be installing the better coolers ?
For folding? Yes!
Also you need to keep in mind it will be quite the heater, I know from experience with the 2P version that it will produce quite a lot of heat. For , the coolers my primary concern will be quietness as it will be an open case system. However I don't think I will install Linux on it right away, but go with Windows Server as it will also be my primary, everyday rig. The chips coming on it, Opteron 8384 clocked at 2.7 GHz will probably be at the limit of -bigadv WU finishing time, but time will tell. Rig is on the way, supposed to be here sometimes next week. For Windows Server 2008 R2 the good news is that it works just fine with regular Win7 x64 drivers.
