$500 Budget PC Build

[clipa]

Hey everybody, I'm looking to build a computer for office apps, movie watching, and maybe a little bit of WoW, but I'm happy with low graphics settings so long as the framerate is above 40 FPS.

I'm just building the box; I have keyboard, mouse, monitor, OS.

Price is a major concern. I'm budgeting $450-$550, including tax and shipping.

It's essential that the computer be inaudible when just running office applications.

Here's the build I'm considering:

CPU: AMD Phenom II X4 925 2.8 GHz (http://www.newegg.com/Product/Product.aspx?Item=N82E16819103656)
Mobo: ASUS M4N68T-M (http://www.newegg.com/Product/Product.aspx?Item=N82E16813131626)
Memory: G.SKILL Ripjaws Series 2x2GB DDR3 1600 (http://www.newegg.com/Product/Product.aspx?Item=N82E16820231277)
GPU: [GIGABYTE GV-R467ZL-1GI Radeon HD 4670 1GB 128-bit DDR3 (http://www.newegg.com/Product/Product.aspx?Item=N82E16814125277)
HDD : Seagate Barracuda 7200.12 ST3500418AS 500GB 7200 RPM SATA (http://www.newegg.com/Product/Product.aspx?Item=N82E16822148395)

Wireless: GIGABYTE GN-WP01GS PCI Wireless Adapter (http://www.newegg.com/Product/Product.aspx?Item=N82E16839121008)
Power:OCZ ModXStream Pro OCZ500MXSP 500W (http://www.newegg.com/Product/Product.aspx?Item=N82E16817341016)
Case: Apex TX-381-C Black Steel Micro ATX Tower (http://www.newegg.com/Product/Product.aspx?Item=N82E16811154094)

I was fortunate enough to find some deals on Newegg, so it comes to $531, shipped. What do you guys think? Any suggestions?

I think it's great.
What kind of wireless router are you using?
