Alright, so take off the cpu cooler?better psu, and the corsair. also, the ssd is just for booting, while the 500gb will be for storage, etc. Yes, this will be for gaming, LoL, WoW, Rift, Saints the third, metro, etc.
Just be aware that the video card might gate your performance a little (not much) on this build. If gaming is really important I'd drop the SSD and put that extra cash into a better card. If you're spending a lot of time in regular desktop apps, stick with the SSD.
Definitely go with the Antec Neo power supply.
