iMac 20″ Intel 2.66, 4G RAM, 250GB HD, Mavericks & asstd software £399
The iMac Core 2 Duo 2.0 20-Inch (Aluminium) features a 2.66 GHz Intel Core 2 Duo processor (T7300), with two independent processor cores on a single silicon chip, a 4 MB shared level 2 cache, an 800 MHz system bus, 4GB of RAM (667 MHz DDR2 SDRAM, PC2-5300), a 250 GB (7200 RPM) Serial ATA hard drive, a vertically-mounted slot-loading DVD+R DL SuperDrive, ATi Radeon HD 2400 XT graphics acceleration with 128 MB of GDDR3 memory, a built-in iSight video camera, and built-in stereo speakers underneath the 20″ glossy TFT Active Matrix LCD (1680×1050 native) display designed to “bounce sound off the desk below”.
Connectivity includes three USB 2.0 ports, a Firewire400 port and a Firewire800 port, built-in AirPort Extreme, and Gigabit Ethernet, as well as mini-DVI, which supports an external display in “extended desktop” mode.
Externally, the Aluminium iMac Core 2 Duo models feature elegant aluminium cases and have a glass cover that joins precisely to the aluminium enclosure creating a virtually seamless front surface – compared to white plastic cases used by the models these replaced. Additionally, the Aluminium systems were paired with a new ultra-thin aluminum Apple Keyboard (0.33 inches at the front edge) based on the polarising 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 Firewire400 port and Firewire800 port.
