Question about my almost ready to order pc

the link doesnt work, but what i can comment is that a 700W isn't needed for a normal setup, and not even an SLI setup. a 650W would be enough for SLI, and 550W enough for a single card.

HD - Should I get a Raptor, or 2 7200 rpm HD's in RAID 0, If I get a Raptor, I'll eventually get another one and put them in RAID 0. Also, what exactly do I need to set up a RAID configuration?

The Raptor is still the fastest desktop hard drive, but only just. If you want a decent amount of space for your money, get a modern 7200 drive.
Here's a good review from tomshardware that has a lot of benchmarks for a lot of the most recent drives:

Forget RAID 0 - it puts your data more at risk and makes your life more complicated for little real life gain.
For real high end speed, you could look at a flash disk, but these are still really expensive per gigabyte. Here's another good review from tomshardware that shows you the latest out there:

GPU - I'm gonna get an 8800 GT, so do I want to get the Company of Heroes or ET: Quake Wars bundle?

It's up to you, get the game that you want!

PSU - 700W should be enough, right?

Yes

SFX Card - What should I get, I have no idea? I' was thining of the fatility one, but it's not compatible with vista or something? I dunno, since I'm gonna be doing some recording if that fatality card would be the best choice. I'll probably just stick with onboard sound for now
Onboard sound is pretty damn good now. Try it and see - you can always add a soundcard later.

500W-ish for a single modern GPU. 700W+ for SLI. 1000W+ for tri SLI or quad CF.

That display has a 1920x1200 resolution. I suggest at least 8800GTS. GT with some low-to-med video settings. Also, I suggest you use HDMI instead of D-SUB (analog). Get a DVI-TO-HDMI adapter.

The rest looks good. You got the money. Go for it.
