When my DP G5 PowerMac died, I was left with a 20-inch LCD Apple Cinema Display doing nothing as the replacement G5 PowerMac used a dual DVI connection setup. I quickly swapped it for the 17-inch
LCD Apple Studio Display, which then was added to a friend's big collection as I owed him a few favours. Both of these displays are the acrylic bodied things using the ADC connection (data, video, USB, audio & power). Right handy having a pair of USB 1.1 ports & a pair of FireWire 400 ports on the back of the display.
