I have installed windows7 to test out the system and find out if anything is wrong with it. Currently I am running the 6300 @ 4,4 Ghz with a very nice Arctic Freezer A30 cooler. The case arrived today and it took about two hours to finish with the cable management and the rest. The zalman Z9 plus came with 3 120mm blue transparent coolers (front to HDD, side to GFX card and Top to CPU), another 120mm white reflecting blue in the back to outside. Quite something if you ask me! I placed the thermal sensor on the southbridge. Three of the coolers are manually controlled from the front of the case. I am using futuremark tests to see how the PC is behaving and no errors so far. After I am pleased with the results will install VM and then play with linux and windows server. Will report back.
