I just upgraded my system with a brand new motherboard, CPU, and RAM, so here's my semi-new build:
Corsair 800D
Corsair AX1200
EVGA x79 FTW
i7-3960x @ 4.4GHz
Corsair H100 cooler
32GB (4x8GB) Corsair Dominator DDR3-1600 (yes, 32GB 😀)
2x EVGA GTX 580 superclocked
Asus Xonar Essence STX sound card
Assorted hard drives (including an 80GB x25-M for boot, 2x300GB velociraptors for apps, and 5TB of other storage for various files)
Cable management still needs a bit more work (I just finished the reassembly, and have been stress testing the overclock rather than cleaning up the cables), but it still looks fairly good if you ask me...
