Aloha Mi Amigos.
I'm not a noob hackintosh'er for starters, I currently run SL 10.6.3 ( I think, at least that's what it says on the green sticker on the box, not sure if I've updated since )
And I dual boot it on a HP Dv7 1020ea with Win7 , the only thing that isn't working for me is the subwoofer, which I'm pretty proud of if I do say so myself ( BUT THAT SUBWOOFER NOT WORKING KILLS ME )
Ahem, anyways, I'm looking to build an i7 Mac coupled with water cooling to get a nice 4GHz i7. Specs are as follows and I was wondering if you guys could grind it to dust in what does and doesn't work, and what can work with fiddling.

Specs are:
Intel Core i7 950 ~ Processor
Corsair XMS3 - 8GB, 2x4GB. ~ RAM
ASUS P6T Deluxe V2 ~ Board (yeah I wanna know as much as possible about this as I know it sorta works)
Intel X25-M 80GB ~ SSD for Mac Install
Asus Xonar DS PCI ~ Sound Card
Asus GTX 470 1.25 GB GDDR5 ~ Graphics card. Just for clarity here's the link  (ASUS ENGTX470/2DI/1280MD5 - Graphics adapter - GF : 90-C3CHA1-X0UAY0KZ - Komplett) 
Then just a 1-2TB drive for other storage and a Windows 7 seperate install.
Every bit of help is appreciated, I know the HCL has some awesome resources, but I'd like opinions, trade-offs. etc etc. Thanks again for taking the time to read the post =D
