Let's see here...
PSU: A no-name PSU, so questionable build quality there. I suggest using Corsair, Silverstone, OCZ, or PC Power power supplies. Don't cut corners with a PSU, it is the heart of the system.
Case+CPU: The combo discount isn't really that much. For better performance, go for the Phenom II X2 line as it has more power behind it. However, if cost is an issue, that Athlon II will work nicely in general PC operations.
RAM: I wonder why the faster 1600 RAM is cheaper than the 1333...
Mobo+OS: Great choice.
HDD: I suggest getting one with a 32MB cache like the Western Digital Caviar Green WD5000AADS 500GB 32MB Cache
ODD: A simple drive is all you need, and that is one such drive.
GPU: For general tasks, that will do well. If you were a gamer, I would go for the 4870 or the 5770.
