This one was recieved in 2007 as a frantic replacement for my custom built after it was taken down in a power surge. This one does not belong to me, but I've had it for years (much longer than I should have, to be honest). It has been thrown into service as a main computer several times (my L300D comes to mind here, as does the two times when my brother had to have his machine replaced).
Processor: AIM PowerPC 7447a (G4) @ 1.5 GHz
RAM: 2 GB DDR
80GB Seagate hard drive
It is scratched, and has some case damage+missing screws.
OS: Mac OS X 10.5.8
Current status: In use as a presentation computer for my live streaming activities.
