1) too much ram, 16Gb is plenty.
2) throw away the 1Tb HD and go SSD only.
3) instead of spending that INSANE amount of money on a corsair case, go with the Fractal Design R4 (or one of their even cheaper yet superb models)
4) you dont need a sound card
5) you probably dont want WiFi. i hope you don't want WiFi. a wired connection is always better.
6) you dont need a case fan.
and also i would go to a 1070, because price/performance its better.

i would also budget in a Zowie FK1 or AM-1C, a Silent Monsters XXL mousemat, and whatever monitor you can afford, preferably with ULMB@120Hz+.
a mechanical keyboard would also be nice, maybe tenkeyless.
