I still haven't got my mac. I've been looking around at used ones, and a G3 iMac with pretty much the same specs as a Powermac G3 is a lot less and includes a monitor. So my question is, will a G3 iMac, probably 300-500 mHz with like 256-512 RAM be able to run OS X at a bearable speed? All I really need it for is to browse the web with cable internet, download and listen to music, research/type papers, and watch movies if it has a DVD player. Thanks.
