I really like the G3 because it is fanless. I can chase my dream of a totally silent system that way (still have to figure out something for power supply fan).

G3 works A-OK for MorphOS, although I would say that playing DVDs does get choppy. I had hoped that mPlayer would be optimized some more and that this would improve performance. Maybe that'll still happen. Should we start a bounty to optimize and improve mPlayer?

Anyhow, G3s are also very power-efficient, so I like this too.
