You might not even have to replace the psu. The athlon II 215 + a gso card would probably pull 100-125 watts together.
I didn't check antec pricing but it's hard to beat the corsair 400 which has been around $30-40 after rebate. You won't find much, other than junk, that can beat its price.
The top is I believe the 1 you mentioned. The next 1 has more juice with 450w. If I added a video card and sound card. Which psu do you suggest? Also video card wise. I am still not sure of a good match for this system?
