This machine started life as a stock PowerMac G4 dual 500.
Expanding needs for the PowerPC Gaming Lounge meant a creative solution was required.
This server is in 24x7 operation as the official PPCGL file repo and Quake server.
It has 2x mirrored RAID sets (each on a dedicated PCI SATA controller), SSD system drive, and a Gigabit NIC from an XServe. It's running 10.3 Server.
Yes, I could have purchased an XServe, but I wanted a project. And XServes are *very* loud. With this setup I have fairly stock / easy to find components.
