It sure had been a while since I worked on an Apple PowerMac G4. Tonight, I did so on two at once. The blue one is from April 1999, is a G4 450 Mhz and was bought the same month my 1st son was born. The grey one is, I think, from 2001, is a G4 887 Mhz and was once a web server running Yellow Dog Linux. Both are fully functional and my mom is still using the newer one.
