I impulsively went to Microcenter to look for upgrades for my linux desktop, since that was my bribe for myself. It looks like the spare processors I was going to use are old enough that I can’t use them with a new motherboard, so I didn’t think I’d get out of there for less than $150 (motherboard, processor, and power supply–I have RAM and other parts). Woe!
On the other hand, perhaps Microcenter isn’t the best place to do this. (Funny how whenever I’m looking at pre-built boxen I can’t get the salesboyz to leave me alone, but when I’m looking at components I can’t get their attention.) I think I need to go to a real computer part store instead.
