Ooh, you found better deals than I did Vic!

CPU: I didnt even think about checking Ivy I5's, so I chose a well known/used Sandy.

RAM: I'm partial to Corsair so I stuck with that for RAM.

HDD: I decided not to go for the caviar black because of the $20 difference.

GPU: I prefer the video card I chose over the one you did, personal preference really.

Case: Case doesn't look great, worth the 15 dollar savings I spose.

PSU: Corsair makes good PSU's, I just didnt see this one. I like that price for the bonus wattage.

Drive: Didn't even think about a disk drive.

[MENTION=2462]MetaSeraphim[/MENTION]; I don't imagine you've built a PC before, but as you can see it is quite a viable alternative to purchasing prebuilts. Both of the builds I and Vic have made are pretty good, and are cheaper than the one you're looking at.
