While officially a "build-to-order" upgrade for the iMac "Core 2 Duo" 2.0 17-Inch (Late 2006), the iMac "Core 2 Duo" 2.16 17-Inch is also treated as a distinct model for user convenience. The two models are identical except for the processor speed.
This iMac is powered by a 2.16 GHz Intel "Core 2 Duo" processor (T7400), with two independent "cores" on a single silicon chip, a 4 MB shared level 2 cache, and a 667 MHz system bus. It includes 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", and ATI Radeon X1600 graphics acceleration on a PCI-Express bus with 128 MB of GDDR3 memory. Also featured are a built-in iSight video camera and integrated stereo speakers below the 17" TFT Active Matrix LCD (1440x900 native) display, which is designed to "bounce sound off the desk below".
Connectivity options include three USB 2.0 ports, two Firewire "400" ports, built-in AirPort Extreme, Gigabit Ethernet, and a mini-DVI port that supports an external display in "extended desktop" mode, not just "mirrored mode".
