Something similar to this would work if your concerned about money.

After rebates it's like $680 and that's everything minus case, cpu fan, a vanilla dvd drive and vista 64 which you could probably get at a discount from your school. You could swap the ssd for just a normal 10k rpm drive or just use the 120g. That system is very similar to what I'm running but with a better graphics card. Mind you this was built with budget in mind and if you play on a decently populated server you will get mediocore frame rates in org and I doubt dalaran would be feesable times 5. But that could be solved by a simple graphics upgrade. You can snag a x260 for $234 basically another 100 bucks.
