Keep in mind you only get 1 copy at the student price...
4 GB are not needed just for WoW, but I wouldn't put any less in a new build. In fact, this build is probably overkill just for playing WoW. It's requirements aren't that high. If they were, not as many people could play it. Really, this is a good all around gaming build for the budget.
To just play WoW, you could probably drop to the cheapest AM3 CPU, a tiny HDD (80 GB would be way more than you need for the OS and WoW), the bottom of the barrel GPU and a 300W PSU well under $500. In fact, I'd be willing to bet any Pre-built PC you could get from Dell or HP or whoever would be good enough. Just saying it's for WoW is setting the bar basically on the floor...
You might want to consider looking into if you can play on your laptop, and get a monitor, keyboard, and/or mouse to play it with. It will be cheaper, and probably won't affect your experience.
I will say that the best thing about this build is that it will be good in the future and for other games. So when you realize you're wasting your life playing WoW, you can play other games. Or when the next time wasting scheme comes around, you can do that too...
thanks for all the links, that was great.
reading the reviews of the memory some people really hated it, does that mobo have the ability to adjust mem voltage that high?
PS I selected the Phenom II X2 550 because it had free shipping and the other chaged $6 bucks,
