Well, in that case, I'd modify the build for AM2. Wouldn't add too much. Maybe $50 or so. However, you'd have to change the memory to DDR2, but it's about the same price as DDR. Last comment: You can get a better power supply from Asus for that same price. I'll link in an edit.
EDIT: For optical drives, Samsung is good. Very dependable. Get one of those and save some money.
