Things i would change:
cpu cooler: no NH-D14? hmm assuming they won't fit with the Ripjaws that's why you haven't got it listed (any possiblity of having the ram changed so a NH-D14 will fit?)
case: personal choice but i wouldn't go for the 650D, other cases that i can list if you want (just write what features/kind of cases you like
ssd: heard the ocz agility 3 ssd's are pretty crap, had a member here who said his one started acting up after 4 hours of use and the website he ordered it from had 100's of returns (however it could have been a bad batch the website received)
hdd: i'm not so keen on hitachi drives, why not go western digital or samsung
psu: hmm not sure about ocz psu's don't have any experience, although i would go with: corsair / seasonic / nzxt hale (tom likes it)
side note on cpu: lots of debate about 2500k vs 2600k, however if you're going to do cpu heavy tasks most of the time then stick with the 2600k otherwise, if it's gaming mainly go for the 2500k as it's better for gaming and you'll save a pretty penny.
