Just wanted to chime in and share my rig right before the new case teardown. The case was the only thing left from my old computer build (939 or 478, I forget which), however I've already replaced it with a HAF-X, and I'm soon going to be replacing the H50 with a full-custom watercooling setup.
The H50 as shown was 1 Gelid fan, but now is running push/pull with two Gelid FN-PX12-15 120mm PWM fans. They move a ton of air and I never hear the fan making noise, only the rush of air through the radiator. It keeps my 2600k @ 4.3ghz at 33c idle and 74c load. I just LOVE using PWM fans with the Asus Suite II fan profiler, so that I can run a profile that keeps it relatively silent until it gets very hot. When I go to watercooling, I'm working on a way to ghettorig Panaflos to work with PWM on a 3x120mm radiator.
