I didn't read this thread, so I'm sure someone has already said these things
CPU is overpowered, unless you really want those hyperthreaded cores for video encoding/rendering you should get an i5-3570k
Don't cheap out on the ram, get 8gb of at least 1600mhz
Don't cheap out on the hard drive, just spend the $95 dollars for a caviar black 1TB. It's well worth it, much faster read/write
Don't cheap out on the PSU, even though you haven't added it to the partpicker. This is just a precautionary suggestion
If you want to overclock, I would recommend the hyper 212 evo. It's only $35 and it would allow you to boost your cpu clock speeds a good bit without sacrificing any temperature
