Seen on Twitter, photos of a Macintosh Teapot 4:30.
These were posted by a Polish museum dedicated to Apple, showing plenty of photos of this machine. The first images serve as a teaser (I removed a few rabbits), while the others suggest it is a prototype of the Centris 660 AV (I believe). The version I had previously seen contained a prototype of the Power Macintosh 6100.

The motherboard, clearly from a Macintosh 68K
