I was thinking about Apple TVs and the first generation one with the Pentinum CPU which you can install OS X on it and use as a desktop, then I was thinking of Mac Minis. Then I had an idea. How bout use a (old) Mac mini as an Apple TV? You'd use Front Row and it would be just like an Apple TV, except you can exit Front Row and use it as a desktop too with remote keyboard and trackpad all-in-one thing. But which Mac Mini would be good? I was thinking a PowerPC Mac Mini because they are cheap and run all you need (all you need for using a Mac Mini as an Apple TV is OS X Tiger because it has Front Row (I think? If not then OS X Leopard)) But the problem with using a PowerPC Mac mini is that they are quite weak so I don't know if it would work well. So here are the questions. Is an old G4 Mac Mini powerful enough to play movies, media, etc, in Front Row? Can it play 720p and 1080p, etc? I've heard they can't... If not, can an Intel Core (1) Solo/Duo (the first Intel Minis) play HD movies? If not, can the first Core 2 Duo Mini play HD movies? If not, what's the first Mini that can?! Also a few other questions... iBooks/PowerBooks/MacBooks/MacBook Pros, without the display, would also be good as a TV box, because they are thin and flat and would fit in places, and they also have a built-in keyboard and trackpad, so you can control the TV. What first iBook/PowerBook/MacBook/MacBook Pro can play 720p or 1080p movies in Front Row? ----------- Edit: I just realized another benefit of using a Mac mini as an Apple TV! The Mac mini would have an optical drive so you can play DVDs! Apple TV's don't have optical drives! Awesome! Mac mini is the best! ----------- Edit 2: I found out that the G4 minis don't have IR receivers. Though that is quite bad, it's not the end of the world. You can use a USB IR Reciever. But this is just another reason why an Intel would probably be better.
