the server is an old Powermac 5400, but I am in the process of moving it to a beige G3 (G4 733mhz upgrade) with a 120gb SATA hard drive. The 5400's are starting to fail frequently, though I have 10 spare motherboards left. : They are nice because the AIO design doesn't take up much space--- and with my living situation, footprint is very important!
