I also don’t approve of this:

But it is mitigated (slightly) by the fact that one of the people responsible for doing this to a G4 Cube at least put the (working!) parts up on eBay.
Here, incidentally, is my new-to-me G4 Cube. Just waiting for the (annoyingly non-standard) power supply to arrive before I can set it up, but I’ve seen it boot up.
(The G4 Cube is, of course, in the design collection at the NYC Museum of Modern Art.)
