The differences between the Antec SLK3700 AMB & BQE are not that big. Your choice depends on how silent you want your computer to be. If you go for as silent as possible, then the PSU in neither case is good enough and you will probably suspend your harddrives. Then you should choose the colour and price you like. If you don't want to mod your case, then go with the BQE. It's PSU makes less noise and it has rubber grommets to mount your harddrives.
The top ranked heatsinks are the Zalman 7000 models
and the Thermalright SLK-900U/A
. Thermalright has some improved versions of that heatsink now: SLK-948U and SP-94/97
The Panaflo fans are silent (at least the ones made in Japan) and very cheap in the US.
