Thanks guys

I don't see any problems with the case, mobo & video. If you're worried about the psu,

Nothing is "wrong" All will work.
The RAM is good, sorry, I didn't read it correctly.
The PSU is also good, well 600w from a lesser brand is not enough.
Get a better PSU if you want to add more / hungry devices later.
Also, might want to upgrade the DVD burner, if it's not DL.

Your CPU might be "too" good. A E6400 might be good enough if you. Then with the $100 saved, get a quad core later or a killer CPU heat-sink.

Confused enough?
I can help more if I know what this is used for..
