All iMacs before the G4 iMac have a power button on the front.
None of the iMac keyboards had a power switch on the keyboard. This went away when the first iMac was released with a USB keyboard.
What type of iMac are you planning on getting that does not have a power button?
Every Mac ever made has a power button.
I was wondering if all G3 imacs with a 500 MHZ processor had the power button on the monitor. I know the older ones had the button on the keyboard.
Also, would I need a keyboard with a power button in order to turn on an iMac with no power button?
Thanks a bunch guys, this forum has always come through for me : )
