So, a couple weeks ago I bought two Power Mac G3s for $50 from some guy on craigslist. (Yes, $50 for BOTH) He said one crashed when he tried installing OS X Tiger. So what did I do? I took the hard drive out of the "bad" Mac, stuck it in the "good" one, installed OS X on the hard drive, and then stuck it back in the "bad" Mac. It couldn't have been easier. I then sold that "bad" Mac to a friend of mine for $50, which left me with another Power Mac G3 for that I had gotten for "free". Another person on craigslist I had bought from before said he'd sell me a Power Mac G4 AND a 17-inch Apple CRT Studio display for $40. I jumped on it. And now a local computer store is going to give me $40 for the Power Mac G3. So basically, I've worked myself up to getting a Power Mac G4 and 17-inch Apple CRT display for free. If you check craigslist daily and jump on the good deals, there's definitely money to be made in fixing up Macs and selling them!
