Well, looks like I'll be getting one from im_to_hyper on MacRumors, a lime one and now I'm kinda obsessed. This will be my primary Apple desktop, and now I think a 2nd one would be grand! Open to G4's as well! So...
Looking into getting one for my son, it'll be his first Apple desktop. I heard these are great for students, he's in 6th grade so really nothing that would be too much for him. Pretty much a G4 or G3 that'll take care of his homework and media needs. Plus, got himself a Nano traded for his PSP so he's in love with Apples. So the specs for a G3 would be:
10.3 or above...
As for a G4...
10.3 or higher
LMK what you have!
