thanks for the info...Powermax is advertised here but I just forgot the name. I'm Looking for referb G4 systems. I am trying to talk some one out of upgrading a 333G3 and into getting a referb Mac insted. The Zif upgrade cards dont suport OSX and by the time he spends the cash on everything he will need, plus my labor ... it wont be worth it. Hes all about the pro aduio and needs an upgrade.
