Sub $500 build

[DragonMaster]

Hey guys, I am trying to put together a parts list for my sister's boyfriend. He's wanting a new desktop computer, and is trying to stay under $500. I need some suggestions on parts because of the low budget. I'm used to the $800 range. Here's a list of his criteria for the build:

-at least 2Ghz processor
-2GB of ram
-don't need any larger than 100GB hard drive (80GB would do the job just
fine)
-2 drives, including dvd and dvd-r
-card reader
-wireless b/g network card

He is just wanting a tower build, no monitor, keyboard, or mouse.
I plan on using Windows Media Center for an OS. (I won't install Home edition, and I'm not impressed with Vista yet.)

Any suggestions are welcome. I keep going over budget. Thanks.

Sonata II - $50 after rebate
Intel Pentium D 915 - $83
Asus P5L-MX - $77
2GB Corsair ValueSelect DDR2-667 -$100
Seagate SATA 80GB - $44
LiteOn DVDRW and DVDROM - $56
Card Reader - $20
Wireless Card $20

That comes out to just about $460, and it gives you plenty of headroom to upgrade later.
