Quick thing: Your video card is a GeForce, but the motherboard supports Crossfire. I'm a bit out of the loop, but I believe Crossfire is ATI's rebuttal to nVidia's SLI. I don't think this is a problem unless you plan on adding a second GeForce card and linking it with the first in SLI, which, I suppose, won't work. Again, not a huge deal, maybe something you considered, but just something I want to throw out.
Save yourself $40 and have a blast building it yourself
I think you might be able to find a better video card. I'm not an authority on that, so I'd wait for Lasereth or someone more in-tune to comment on that.
Also, what site is this? The hard drive prices seem very good!
Congrats on graduating and landing a job - this is a great present! I built a computer a few years back, and I plan to keep it running lean and do exactly what you're doing! What did you major in and where will you be working if you don't mind me asking?
