You can breath new life into your older, single processor G4 PowerMac with this easy upgrade.
This is the OEM 500MHz Dual Processor G4 from Apple. It includes processor card, heat sink and clips.

It will work in all Gigabit Ethernet PowerMac's and most Sawtooth PowerMac's. The earliest SawTooth's do not work with dual processor's. You can download the UniNorthASICChecker application from MacUpdate to confirm that yours will work: http://www.macupdate.com/info.php/id/13551/uninorthasicchecker
Asking $50. Installation is trivial, but if you bring your (working) G4 tower I'll install and demonstrate it for you.
