This is what I got: http://pcpartpicker.com/p/vdCn
Except I got a different hard drive at the same price. It's some sort of Western Digital 1T drive SATA 6G 64M. I also got a DVD drive, but I'm hoping that won't make any difference with the case I got.
Here's what my friend said re the power supply I got: "Your power supply has one 6-pin PCI-Express power connector (the kind of cable used to send power to a video card). If you were to buy a standalone video card, it would likely need two such connectors -- either two 6-pins or one 6-pin and one 8-pin. You might want to look into trading up a bit"
Which one should I get? I want one that's pretty good quality.
