used computers (Flanders NJ)

I'm in need of used computer, pretty much any none apple computer would work. I'll even taken broken ones for parts. I run a small probono project (I found it myself) where I rebuild and donate computers to worthy causes. In this case a home schooling class. The computer they gave me to fix, is beyond repair, at this point. I'm trying to replace it for them probono as a family member is dealing with chemo and can't afford to replace it. Any computer, will do including apple product as someone else is doing the same thing with them. Any donations would be greatly appreciated.
