Si I picked up a G4 1.42 dual on ebay with 2 gb memory, 80gb hdd. So I install 500 gb, 250GB, and 2- 40gbhdd's. I picked it up on ebay for 299.00 + 15.00 shipping (got a coupon on ebay for 1/2 shipping) my question is compared to G5 how long do you think I can keep this going? I have a Color Classic with a presto plus in it and it still is good but surfing the internet is dogg slow...
