Hello Guys, I have got a question: I have got the 700 MHZ PowerPC G4 15'' iMac (Cube), and also the 21.5'' iMac 3.06 GHz Intel Core 2 duo etc.. I only use the 21.5'' Mac, because it's just much more better, that's why the G4 is actually just useless.. But I don't want the G4 to full my nice space on my desk, that's why I have got the question, is it possible to use the G4 as a second Monitor for my 21.5 iMac? I know it has something to do with 'outputs' and stuff, but I don't really get that. I would appreciate any help..
