The iMac Core 2 Duo 2.0 was the second iMac design to use a flat-panel display. It featured a 2.0 GHz Intel Core 2 Duo processor (T7200) (with two independent processor cores on a single chip), 1 GB of RAM (667 MHz DDR2 SDRAM, PC2-5300), a 160 GB (7200 RPM) Serial ATA hard drive, a vertically-mounted slot-loading DVD+R DL SuperDrive, a built-in iSight video camera, and built-in stereo speakers. The flat panel display was a 17-inch TFT Active Matrix LCD at 1440×900 pixels.
Ports on this iMac included three USB 2.0 ports, two FireWire 400 ports, Gigabit Ethernet, and mini-DVI supporting an external display in extended desktop mode (rather than only supporting mirrored mode). This iMac also included built-in AirPort Extreme support.
