Just like to say if you go for HASWELL CPU (i5-4670K) then chose XFX 650W PRO, cause XFX 550W is not compatible with HASWELL CPU. And you can chose Corsair PSU except CX, VS, RM series they are not good.
A high end system needs a decent CPU, MB, GPU, PSU and HDD/SSD mainly, by no means GTX 760 or HD 7870 is a high-end GPU.
I would chose Dell S2240L/S2440L as Monitor. Cooler Masters 912,922, 932, HAF X, Trooper, or Corsairs 200/300/400 and so on cases are good one, I would chose that over NZXT case, they rather look/perform flimsy. Good luck.
