Apple iMac Intel AluminumThe iMac "Core 2 Duo" 2.4 20-Inch (Aluminum) features a 2.4 GHz Intel "Core 2 Duo" processor (T7700), with two independent processor "cores" on a single silicon chip, a 4 MB shared level 2 cache, an 800 MHz system bus, 1 GB of RAM (667 MHz DDR2 SDRAM, PC2-5300), a 320 GB (7200 RPM) Serial ATA hard drive, a vertically-mounted slot-loading DVD+R DL "SuperDrive", ATI Radeon HD 2600 PRO graphics acceleration with 256 MB of GDDR3 memory, a built-in iSight video camera, and built-in stereo speakers underneath the 20" glossy TFT Active Matrix LCD (1680x1050 native) display designed to "bounce sound off the desk below".

Connectivity includes three USB 2.0 ports, a Firewire "400" port and a Firewire "800" port, built-in AirPort Extreme, and Gigabit Ethernet, as well as mini-DVI, which supports an external display in "extended desktop" mode.

Externally, the "Aluminum" iMac "Core 2 Duo" models feature "elegant" aluminum cases and have a glass cover that "joins precisely to the aluminum enclosure creating a virtually seamless front surface" -- compared to white plastic cases used by the models these replaced. Additionally, the "Aluminum" systems were paired with a "new ultra-thin aluminum" Apple Keyboard (0.33 inches at the front edge) based on the polarizing keyboard design introduced with the MacBook.

Internally, some "Aluminum Core 2 Duo" models have faster processors than their predecessors, but all have a faster "Santa Rosa" motherboard design with an 800 MHz frontside bus (up from 667 MHz), additional RAM capacity, and both a Firewire "400" port and Firewire "800" port.
