I figure I'll look them over, fix what I can and then scavenge and trash what I can't..
One of the units is fairly new - a quad core i5 w/Win7... The other two seem to be old single core units but I haven't looked them over yet. Hopefully whoever owned these things made it easy for me by not password protecting their windoze startup.. ;-)
I gots me some fixit projectks... ;-)
Easiest fix in the list is the HP printer. Heck, even I probably have a power supply that would work for it.
Ficksit progeckts are lots of challenge!
