The real money in a desktop, in my opinion, is from the high grade boards, the RAM, and the CPUs (and of course the wire). Those are the gold platinum and palladium containing parts that people want to refine, and that can be sold on ebay for $$. Really, when you pull that stuff out of there, the steel that is left is only worth maybe $.50-$1. go on ebay and check out what they are selling for!
