A nice idea for a “retired” Mac: new life as clocks.
Here are two versions using the side panel and front cover of a G4, which sort of looks like a giant Swatch but has an operating CD drive door and zip drive opening.
The creator is a guy (handle: pixelthis) with a fondness for all things Apple who has been taking things apart since the day he could walk and occasionally putting them back together.
These Mac clocks run about $60 each, available on Etsy.
His other clocks made from computer hard drives, bike wheels and bike gears are also worth a gander..
