if they work or is an easy fix sell it whole, most computer repair places around me buy them, i had 2 with broken screens recently, sold one for $140, the other older one for $50, so Im assuming that I wouldve gotten MUCH less for scrap. when you come across them ask whats wrong with them, or try and turn them on yourself. Desktops are not worth trying to sell whole unless you come across pretty new ones, like less than a year old
