A few things did stick out at me.
First, the PSU that comes with that case is awful. You will want to get a separate PSU from a more reputable brand, or get a case/PSU combo from a more reputable brand (though not many reputable companies make case/PSU combos... Antec is the only one that comes to mind). Given a budget, we could help by giving some suggestions.
Second, don't get that Raptor hard drive. The 74GB version is very old technology (relatively speaking), and you can get a 1TB 7200rpm drive that will outperform it for the same price (
Samsung F1). If you really want the most speed out of a hard drive, I'd recommend the
300GB VelociRaptor. However, it would make much more sense to put the money towards the rest of the system. For example, as Facedown98 said, if you are into video editing you'd see a nice benefit from upgrading to a quad core CPU, while the benefit of a VelociRaptor would be marginal at best.
