Building new ~$2000 machine

[Neurotoxin]

Hey folks,

I'd like to get your input on this machine, plus any recommendations for a good case that keeps cool and handles well (sound insulation is less important).

Mobo: Gigabyte GA-X79-UD3 (and I know I would need to update the firmware ASAP if BIOS is F7 or below)

PSU: Seasonic SS-660XP2

CPU: Intel i7 3820

CPU Heatsink: Cooler Master Hyper 212 EVO (it fits the tight architecture of this board while leaving ample room for memory)

RAM: G.SKILL Sniper 32GB (4 x 8GB) Quad Channel

GPU: Nvidia GTX 670 (model not yet selected, probably EVGA though)

SSD: Corsair Neutron Series GTX 2.5" 120GB (tools / games / OS)

HDD: WD Caviar Black 1TB (for storage and back-up, might get a bigger one)

Media: LG Black 12X BD-ROM 16X DVD-ROM 48X CD-ROM SATA Internal 12X Blu-ray Combo Drive Model UH12NS29

Thanks!
