I'd keep this mainly, cept swap out the case for the storm scout as it has a handhold you can use to carry it, and perhaps downgrade the RAM to 1600MHZ CL9 ripjaws X series (Save $5), and keep the OP's 500GB spinpoint HDD if he only needs that much, saves another $15 and the power supply for this cheaper and better PSU:
I would get rid of the SSD and put some of that $$ for a higher end GPU, like a gtx570 or 6970. SSDs are more of a luxury and won't really affect your games (only load times, but load times on PCs are quick enough)
Also, won't I need an optical drive? Any good ones out there?
The XFX power supply is better than the TX power supply (According to reviewers) by a country mile. The difference between good and great. The Ripjaws X series is better, and only $70 with the rebate compared to the normal ripjaws series. The XFX 750W power supply can fit 2 560's or 2 570's comfortably.
