Thanks for the advice, everyone. Not necessarily looking for a free hand out, just wanting to get some general advice on what I should look for.

I think for the moment I'm going to continue to browse around and look at options (also see if some come up for sale locally.. theres a few for sale but for some reason people think they are really valuable..). My main curiosity is if there were certain problems that I should look out for with the iMacs.. i know the iBooks had the GPU problems, G5's and the capacitors/ cooling systems, so that way I don't have any unexpected surprises . I don't really know much about the iMac G3s because most of the schools that got them here switched over to PC's and surplussed them off before I really got to use any.

My other question that I thought of, would these be capable of hooking up to a wireless network (Wireless G, protected?).. I know they take the first gen. airport cards.. are their any that also don't accept airports? (assuming that they would still accept a USB wifi dongle would be OK tho).

Thanks for the help!
