Rare vintage 2003 Apple iMac G4 1.25 GHz. 512MB RAM, 60GB HDD. The most beautiful computer ever made!
There is some cosmetic wear, most notably a couple marks on the upper right corner of the LCD (see pictures). They are certainly noticeable, but when you're using the computer I don't find them distracting. The back of the monitor has some black marks, I haven't attempted to clean them. Otherwise, it's pretty clean for a 20+ year old white computer.
I recently replaced the original HDD and Superdrive as they were acting up. The computer is now fully functional and has a clean install of Mac OS 10.4, which is the optimal OS version for this model. It can run 10.5 too, but I think 10.4 runs better.
It currently does not have a wifi card, but you could easily add the Apple AirPort Extreme 802.11g. The RAM can also be upgraded from 512MB to 2GB. Both of these potential upgrades are user-accessible, you simply remove the baseplate to perform them.
Only includes the original power cable, but it will work with any USB mouse and keyboard. It should support Bluetooth peripherals too, but I didn't have any to test with.
