What are you looking to do with the spec? It'd be great for gaming if thse were your intentions, regardless though you'd save yourself quite a bit by getitng yourself the 8800GTS (the new one) as that's just about as fast as the GTX and it's quite a bit cheaper.
I've also heard that that cpu clocks pretty well on pretty much any cooler, so you're on a winner there
4Gb of RAM is always good but your OS won't be able to use all of it unless it's a 64bit OS, so bear that in mind if you've not got one yet or you already have one and it's a 32bit one.
I've got both that case and that HDD and they're both great. The case looks awesome as well and the airflow through it is even better
Only other thing I can fault is that you might want to swap the PSU you specced for somethin costing slightly more such as the Corsair HX520/620 (although 520W should be more than adequate). They're very high quality PSU's form what I've heard, and pretty much everybody recommends them.
It's not so much a bad thing, but I know a lot of people tend to prefer the intel chipsets rather than the nVidia ones because I believe they're more stable and the only thing that an nVidia chipset has which an intel doesn't is SLI support... which doesn't apply to 95% of people anyway
Edit:Fobose pretty much said all of what I said in one line lol
