Yeah, I do know about those longer screws but finding them in black to match everything else is tough to do locally. Hmm...
I'm pretty over-radded anyway as is, so if there's any decrease in performance from having them as pull I don't think it'll matter much. I'll build it this way and if I don't decide to change it as I'm building I may rearrange things when it's time for the annual teardown.
PS - I'm using two loops (I know, I know), one for the CPU (Core i7 2600K) and one for GPU (single 7950 full cover block). Somebody correct me if I'm wrong, but a 360 rad for each should be plenty, regardless of push or pull, right?
