Im selling this computer because I have got a new iMac G5, This iMac G4 is 800MHz, 256MB, 74.5GB, CD-RW/DVD Drive, Mac OS 10.4.11 Operating System Installed with MS Office included. This iMac is in very good condition. Comes with speakers, Keyboard, mouse and power chord

Answer 1

Well, honestly, if I was you I wouldn't buy it.  At this point its very outdated.  You can get a brand new laptop that is twice as powerful for around $500 now.  It's just not worth to spend any money on that.

Answer 2
