Butt Head Astronomer (a.k.a. Power Macintosh 7100)

I personally prefer the Power Macintosh 6100 form factor, but even I can appreciate the goofy personality of Apple’s engineers to tease Carl Sagan with a first-generation PowerPC Macintosh. “Cold Fusion” on the 8100 was probably the coolest name of the series, while the poor 6100 got stuck with “piltdown man.”
