17″ iMac G4 (Early 2003)

17-inch iMac G4The first iMac to reach 1 GHz, the 17″ G4 iMac has a wide aspect ratio “cinema” type screen and displays 1440 by 900 pixels – just perfect for DVDs. Other improvements over the old 800 MHz model include a slot for an 802.11g AirPort Extreme card, space for internal Bluetooth, 64 MB of video memory, a 133 MHz system bus, 4x DVD burning speed, and a 7200 rpm UltraATA/100 hard drive.

Some Leopard users have reported problems with G4 iMacs that have GeForce 2 or GeForce 4 graphics. When the system wakes from sleep, the screen will be completely white, making the computer unusable. This is fixed by Leopard Graphics Update 1.0, which requires OS X 10.5.2 or later.
