> the reason I didn't think about the 12,1 is its an iMac

...as are the 8,1 and the 8,2. In_Correct just wrote "G5" and you also included the PowerMac11,2, which MorphOS is not available for, so I saw no reason to exclude the iMacs :-) (And inofficial versions of MorphOS have been shown on PCIe-based PowerMac and iMac, i.e. PowerMac11,2 and PowerMac12,1.)
