I'm not that good with AMD builds, but look into Gigabyte motherboards as well using the 790GX chipset. Also consider Biostar motherboards as they're good as well.
For hard drive, WD 640GB is good. Also take a look into the Seagate 7200.12 hard drives.
RAM: 4GB of any brand such as OCZ/Patriot/Corsair at DDR800 4-4-4-12 or DDR1000+
PSU and Case: Antec Sonata III (PM Newegg)
GPU: NVIDIA 9800GTX+ or ATI 4850. Since you're in school, your gaming time is actually limited. I also suggest that you don't crossfire in the future. I myself don't like using dual GPUs. Save up your money.
The stock AMD cooler will be more than enough if you're just doing a minor to moderate OC.
Don't forget to use the Hardware Canucks Price Matching function to find lower prices everywhere so you can get a better rig for less price.
Also take into consideration this build:
