17 inch iMac (Late 2006), Graphics ATI Radeon X1600 128 MB, 250GB SATA Disk, Processor 2.16 GHz Intel Core 2 Duo, Memory 2GB 667 MHz DDR2 SDRAM, Software Mac OS X Lion 10.7.5 (11G63). It comes with the apple keyboard and an apple mouse (with code.) The ideal click does not work well in the screen and the mouse has few streaks. I don't use this iMac anymore which is why I'm selling it. E-mail me with your phone number if you are interested, I will call you. Thank you.
