Parts are on their way for the 2nd 4P build. Using all the same part/pieces except the CPU's are Opteron 6176 SE's. I will try for a 20%+ O/C on these chips and will need additional cooling for the VRMs. Will also try to increase the voltage on these chips as well. Aiming for 2.7-2.8Ghz and 1600mhz on the Ram as well. I may eventually upgrade to 1Kw PSU's that are modular for a cleaner appearance.
