Upgrade Tiem.

So I'm going to upgrade my PC in a month. Wanted to run my hardware choices past you guys to see if anyone has any input etc.
Currently I'm thinking:
CPU: Core i7 920 or 940
MOBO: Gigabyte GA-EX58-UD5
RAM: 6GB DDR3 1600Mhz (PC3-12800) Corsair Dominator 8-8-8-24
GFX: 2 x GeForce GTX 260 OCX Maxcores in SLi
SMD: Asus Xonar D2X 7.1
HDD: OCZ Vertex 60GB SSD
CASE: Fractal Design R2 Titanium Grey Case or an Antec P190 + 1200UK
PSU: Zalman ZM850-HP Dual Heatpipe Cooled 850W Modular PSU
HSINK: Noctua NH-C12P Top-Down CPU Heatpipe Heatsink
SPK: Creative Gigaworks 7.1 Speakers
HDD: Drobo + 4 x 1.5TB HDD's
MSE: Logitech G9
KB: Logitech G11 (maybe.. I'ts a bit gay..)
HEADSET: Sennheiser something or other.
In particular some input on the motherboard would be useful as it was pretty tough deciding on that one. Plus I have never had anything from Gigabyte before so don't know how reliable they are?
Also if anyone knows any decent minimalist/not over the top leet omg wtf red led fan gayboyfag cases which have decent sound deadening properties and good airflow shout up.
