Well, my patience has finally payed off! I got a 17" PowerBook G4 from work for free. Its missing all of it's upper case screws, the RAM access door, and a battery. Its in fairly good shape, the only one of the corners are bent. Right now, its running 10.5.8, and has 1GB of RAM. Its the 2005 model with a 1.5Ghz CPU.
