I also have a Mini with Morph OS on it. I bought a G4 MDD a while back just because I always wanted one and the price was finally right.
What are the advantages in running Morph OS on the PowerMac G4 vs the Mini? Just wondering if it's worth reg'ing another copy for it. The demo runs fine on it.
Depends on what model and speed G4 PowerMac you have, compared to which model and speed G4 MacMini you have. A couple of advantages some of the G4 PowerMac's have over the Mini, are more RAM (up to 2gb, but only 1.5gb recognized by MorphOS2.x), L3 cache, better video cards, ability to use a sound card, probably a couple of other advantages that I can't think of at the moment.
Performance on the G4 MacMini is so good, most people won't notice a huge difference, unless you are running software that really pushes the system to the max.
Edit: I agree, it is a good price and someone should take advantage of the deal. Specially if he is including the Leopard Install DVD, that is in the picture, with the keyboard and mouse. The Mini is not yellowed either, like so many of them are.
