well im going to ignore the prices as i know nothing of how much ncix charges... but 315 for a 4870 is a bit much in US
and im assuming your not going to overclock because of the lack of a aftermarket heatsink, and in that case, skip the ddr100 and go for ddr800 with lower timings and voltages... everything else looks good
THEY RELEASED THE HAF 932? tell me how it is it looks sexy... i got the stacker 830
If you're planning on OC'ing the CPU, then you can get a Q6600 easily above 3Ghz with just a simple FSB tweak. So any advantages that the E8400 would have over the Q6600 would be negated by that. Remember you can always OC your CPU, but you can't add more cores.
