May I air some ideas which may be... well, different?
You could save more money and then spend it on good/better components by getting a cheaper, less cool-looking case, as that's all it really does, unless you happen to pick one that has awful air flow and heat retention. I'd prefer two hard drives over a good looking case any day, for example.
And, do you really need five hundred watts? If not, a few watts less, a few bucks saved, to be spent on something else.
As for the heatsink/fan combo, if the sound is tolerable, cooler is better than warmer!
Now, I'm not the hippest on the cpu scene, but perhaps AMD might offer the same or better performance at less cost, still? Someone check me on that one!
Of course, I'm not a real gamer, modeler, nor programmer.
