20 years of service is impressive.
It's souped up a little from the original (started with a 1.2 gb hard drive, now has a 500 gb on a Sonnet SCSI to IDE adapter; PowerMac 7600 with I believe a 603 processor, now has a Sonnet 1 ghz G4 processor upgrade and 9.2.2 of the OS; USB; Radeon vid with three monitors) and will eventually fail, as is the way of all flesh and stuff that flesh builds, but I feel most comfortable with it.
