I have a G4 MacMini that is in stand-by mode for MOS. :-)
I originally bought it as I wanted to start using Mac OSX somehow, yet not pay thousands of dollars to be able do so. :-)
Leopard runs reasonably well on my G4 1.5Ghz MacMini with 1GB or ram, so I would assume that MOS will fly, once released that is. I also upgraded the original CDRW drive with a "Superdrive" (e.g. a proper DVD-RW burner with +-DL support) and I replaced the internal 2.5" 80GB hard drive with a 160GB 5400rpm one. Since this is one of the last PPC Minis released, the on-board Radeon 9200 is also a 64MB vram model (vs the standard 32MB edition).
