Capable, sure... And nicer than what I have actually. However, the newer X2 4200, like in your link, operates at 65w... not 89w, different core, and is an am2 socket with DDR2. Hence, a much faster, new system with room for upgrades, unlike an old 939 board. Hell, I'm running an old OC'd mobile XP with DDR 400. It still handles anything I throw at it. Capability wasn't my point.
LBR... Looks good man.
I would replace that PSU as soon as possible though. I did the same thing with a Raidmax case several years back. It came with a cheap PSU, and it seemed to work well enough... I figured I'd just replace it when it crapped out. I woke up one morning to find it fried, along with my video card, my hard drive and of course, my data gone. I learned an important lesson about PSU's, and the importance of regular back-ups. I was lucky it didn't take my whole system down with it.
I find it very suspicious that they don't show a pic of the PSU's technical specs.
