Here are my selected components:
MB: Asus P5Q-E
CPU: Intel Q9550
GPU: 2 x Sapphire ATI 3650's (I use 3 monitors for trading)
Mem: 2x2gb Corsair XMS2 DHX DDR2 800 (the ones w/ the large heatsinks on them)
Hd: 2 x WD640gb
Power Supply: TBD (probably 650w though)
Case: TBD (after picking all components, will pick case to fit them all)
-Trade for a living across 3 monitors
-lots of home video editing
-Occasional dvd viewing
I don't care about having a frigid PC, I just want it to operate cool enough to last for 5 years if necessary. I'm willing to pay extra for less noise, all else being equal.
-What heatsink/fan should I get for the Q9550? (ARCTIC COOLING Freezer 7 Pro 92mm or the XIGMATEK HDT-S1283 120mm)?
-How many additional fans (besides the CPU fan, power supply fan, and 2 ATI card fans) do I need & where should they be placed? (1 intake in front, 1 exhaust in rear? 2 intakes? No exhaust? etc.)
I recommend Yate Loon 120mm fans. They are pretty inexpensive with an RPM of about 1200. Sound level is about 28dBA, but it is pretty quiet. I have three Yate Loons in my primary PC; intake, exhaust and CPU fan.
These are the one I uses which costs $5 each (black frame, orange fan):
