I was hoping somebody would know for sure if that PSU will work or not. I'm using the guts that are in it now for another pc. So before I go and buy another case, I was hoping to know if I need to buy a new case for my old stuff I currently have ... or if I need one for the XP 1700 system I'm building. See what I mean? If I buy a new case for my old stuff, and then it turns out that the Enhance PSU isn't up to snuff, I'll have to spend a lot more money than I would otherwise.
