Hi Guys! I too have been using a 400MHz Gigabit Ethernet G4 on the Internet at extreme high Internet speeds with no problems. It is still a great machine. Only with the newer graphics programs does it show it's age. The other advantage with these older G4 towers is their upgradeability. Is that last one an actual word? I intend to upgrade the CPU soon with a 1ghz processor. It should give me a few more years of good use. That should cost me a couple of hundred bucks and I have already installed a USB2 card for about $30.00. However I am worried that Leopard won't work on it when it is released in the Spring... Bill
