i recenlty found a Imac G4 model in the trash, it works though but only issue is that it doesnt boot to the desktop. is this worth my time to fix it as i think it is a 2002 model 17in imac. can the memory be upgraded to make a little faster i will also have to buy a keyboard and mouse and also the Bezel on the monitor is broke as well not sure if this can be a good project to fix or waste of time and money.
