Apple iMac Core 2 Duo 2.4 20-Inch (Early 2008)

An Attractive Option for Professionals and Casual Users Alike

The powerful iMac series of all-in-one desktop computers shines brightly in Apple’s lineup as yet another feat of versatility and performance. Arguably one of the most elegant, aesthetically pleasing desktops in existence, the iMac has since its genesis been an attractive option for professionals and casual users alike.

Available over the years in 17″, 20″, 24″, and more recently 21.5″ and 27″ display sizes, with screaming fast Intel processors, top-of-the-line consumer graphics options, and plenty of RAM and hard drive configurations, the iMac can be configured to excel at nearly any task.

From graphic design to programming, from video editing to writing, from business to photography, and — yes — even gaming! The iMac’s have more than enough display space that even the avid multitasker will feel at home, and its sheer speed and power won’t fail to please those engaged in intensive work or play. 

When the recent, tapered edge iMacs were released and Apple decided to forgo inclusion of an optical disk drive in further models, they also saw fit to make it significantly more difficult to upgrade the RAM and hard drive. However, this resulted in a far sleeker and more aesthetically pleasing case design.

Perfect for the home and the office, the iMac has seen heavy use in nearly every avenue of personal computing.

Stable, sleek, versatile — the iMac is yet another example of Apple’s transcendent, artfully engineered personal computers.

Full Technical Specs of this Model

The iMac Core 2 Duo 2.4 20-Inch Aluminum (Early 2008/Penryn) features a 2.4 GHz Intel Core 2 Duo processor (E8135), with two independent processor cores on one silicon chip, a 6 MB shared level 2 cache, a 1066 MHz system bus, 1 GB of RAM (800 MHz DDR2 SDRAM, PC2-6400), 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 vibrant 20″ glossy TFT Active Matrix LCD (1680×1050 native) display.

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

The iMac Core 2 Duo Aluminum (Penryn Early 2008) models are essentially the same as the original Aluminum models that these replaced, with the same housing and glass cover that joins to the aluminum enclosure creating a virtually seamless front surface. The Early 2008/Penryn models are paired with the same ultra-thin aluminum Apple Keyboard (0.33 inches at the front edge).

Internally, the Early 2008/Penryn revision of the Aluminum Core 2 Duo models have faster and more energy-efficient 45 nm “Penryn” processors — compared to 65 nm “Merom” processors in the original Aluminum models — larger level 2 caches (6 MB compared to 4 MB), faster frontside buses (1066 MHz compared to 800 MHz), and faster memory (PC2-6400 compared to PC2-5300).
