I am not sure what kind of cooling one would need in their custom built rig. I am most likely to go with a HAF case or the SILVERSTONE RAVEN RV02-BW Matte black 0.8mm Steel ATX Full Tower Computer Case. Both of these get good air flow as I see it. I will be doing some overclocking of my cpu at first so Im buying getting the hyper 212 (is this good enough). Will i also need to buy HD coolers, Memory coolers, and northbridge coolers?
