Dell Vostro 200 Mini-tower Motherboard

Hi guys,

I'm working on this junkbox Vostro 200, and I can't believe the factory specs that they expect to run Vista with...........512mb of ram? 1.6 gHz Celeron? This was cheap technology over 5 years ago....... Anyway, I'm looking into a processor upgrade for the CU409 Dell motherboard that comes stock with it, but I can't find specs on it ANYWHERE. Anybody have any idea where I can find out what processors it will support? I was hoping it would be a C2D/C2Q, but I may not be so lucky. Anyway, any help you guys can give would be great, thanks in advance.
