I have the build I think I'm happy with. My only concern now (I hope, at least) is that I can't decide between two motherboards, and I hope you guys can recommend which of the two you would get, as well as any other thoughts on my final build. I definitely feel like the motherboard is the weakest part of my build, in terms of what I have done research-wise, and confidence in my choice. It might be a great part, but I'm not sure, and I don't know how to verify that.
All prices are in USD
CPU: AMD Phenom II X4 955 Black Edition

Case: Cooler Master HAF X
DVD: Sony Optiarc Black 24X

This budget is just about perfect for me, as it leaves me enough to pick up Windows 7 with my student discount.
Please, let me know if there are any changes you would make to the build! Otherwise I should be ordering it in the next few days.
