Just some quick notes -- Here's the
recommendation for GPU at your price point. The 560SE or 7770 is recommended at that price point (~$130), with the 7770 being lower-power and roughly the same performance.
I tend to go cheap on the case since it really doesn't add anything to the build, performance wise. As long as there is decent airflow and doesn't break/fall apart, you'll be fine. With that being said, it looks like the Rosewill case you chose should fit those requirements without issue.
If you're planning on doing some overclocking, I'd consider a better cooler for the CPU, but since that's not added in your list, I'll not include that here. But that is the other usage case where looking into the case (dimensions, specifically) would be beneficial.
64GB is fine for a boot drive, though I'd recommend 90-120GB if you want to put a few programs on and not have to worry. The Crucial M4 drive was one of the fastest drives you could buy when it came out. It also had good reviews regarding longevity, but not as good as Intel or Samsung. Granted, longevity is still fairly relative when you're having to write terabytes and terabytes of data (to the point that most SSDs will last 8-10 years, potentially longer, given average use cases).
I've got no real idea how the Rosewill PSUs behave, and would tend to buy something more name-brand. OCZ, Antec, Cooler Master, XFX, Silverstone, SeaSonic, Corsair, PC Power and Cooling, and NZXT would be the brands I'd probably choose from. Additionally, try to find something 80 Plus Bronze, Silver, Gold, or Platinum certified. 80 Plus is fine, though Bronze seems to be the goal to shoot for. My PSU is only 80 Plus certified, and it seems to be perfectly fine so far with CrossfireX and and an overclocked CPU. Here is a
80+ Bronze PC Power and Cooling 500W modular PSU with 2x PCIe power connectors. It's $80, with a 15% off (instant) till the 26th, and a $20 MIR. That brings the total price down to $48 for a stellar 500W PSU with plenty of upgrade options.
