It is not a decent rig... sorry
I would look to make these changes:
CPU: Athlon II X3 440 (The older Phenom's are not very good compared to the newer AM3's)
HDD: Seagate 7200.12 500GB (Higher capacity and faster for a little more)
PSU: Corsair VX550W (This is one area you don't want to skimp at with a low grade cheap power supply.
I would look at Newegg.com come to compare your build to see if you can get it cheaper (they have better combo deals!!)
