As far as $3 a computer that is an awesome price. Ill pay as high as $6 each for quantity. Specialy if I see them having the old 5.25 drives in them. Or pentium4 stickers on them. To me thats means reusable parts to sell on ebay. I usualy dont build working machines for resale but I did have 2 people at work ask me if I had any cheap computers to sell them. They all come to me with their computer questions and refformating of their laptops. SO I think I may build a couple pentium 4 machines to sell for 100 bucks.
