I've had this iMac since new. It's a 2008 24" iMac in excellent condition. Recently replaced hard drive to increase capacity to 1 TB! I've loaded Mac OS X 10.11 - El Capitan and made sure all updates are installed. Comes loaded with GarageBand '11, iMovie '11, LibreOffice (Microsoft Office equivalent), and Firefox browser with privacy plugins installed. Comes with a genuine Apple wired keyboard and a Logitech wireless mouse. Can add another 1TB hard drive (you just need an external case) for an additional $10.
Specs: 24" iMac; 3.06 GHz Intel Core 2 Duo; 4 GB memory; NVidia GeForce 8800. This is an upgraded model from the base. I upgraded the CPU, memory and graphics card.
