Thinking about buying a iMac G5 or powewmac G5 for some older software and general use. How does a higher end G5 iMac surf the web these days? I.e. With Adblock, flash blocker and ten four fox. I just don't know if I want a huge tower if a G5 iMac is sufficient with the web, basic games and lepoard. What do you think? Tell me what you do with your iMac G5. Thanks.
