i am setting up a projector for my church, and i would feel guilty if i didnt set up a mac. so i was looking at the old bubble imac, g4 i think. i can get them real cheap from the university in town. but...what video outputs do they have? vga? dvi? mini dvi? i saw on the apple website that alot of the adapters i would think to use (mini dvi to dvi for macbook, or dvi to vga and whatnot) dont work with those imacs ( http://support.apple.com/kb/TA27346 ). so can anyone tell me what external monitors i can hook up to one?
