I have a 512Mb stick of ram, but I'm not sure if it'd work. I can't remember what the specs of it are. I think it's an A-Data PC2-4200 DDR2, so that wouldn't work. I'll double check though. What exactly are you looking for?
I actually have a gig of ram but I think it can take 2 so that and the better processor although I doubt anybody has it. Maybe the upgraded hard drive as well but I might just get an external.
