One industrious individual in Australia with a surplus of time has managed to put OS X an old 25MHz Centris 650. Yea it can be done. Yea it takes a lot of effort. Yea it performs are poorly as you’d expect.

I’m trying to stop wondering why people do the things that they do, but sometimes it’s difficult.
I’m not knocking the guy, it’s cool for the geek factor but essentially useless beyond that. He has a good sense of humor about it though and I give him him props for his tenacity in the face of antiquated technology.
