The tally: case-2 (front 80mm YS Tech adjustable, rear 92mm PanafloH wired to 7v), HD cooler-3(40mm each), power supply-2 (Enermax 420w FMA), CPU-1 (Zalman 5700), vid card-1 (Thermaltake cooler).
Even w/ all these fans I would not consider this setup noisy. I'm going to do a rebuild soon and will likely pull one of the three HD fans - three just doesn't seem necessary w/ the Samsung SpinPoint drive I'm running. FWIW this Samsung is even quieter than the Barracuda IV it replaced.
