Apple iMac Core i3 3.1 21.5-Inch (Late 2011)

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 i3 3.1 21.5-Inch Aluminum (Late 2011/Education Only) — originally only available to educational institutions — is powered by a Dual Core 3.1 GHz Intel Core i3 I3-2100 (Sandy Bridge) processor with a dedicated 256k level 2 cache for each core and a 3 MB shared level 3 cache. Instead of a system bus, it has a Direct Media Interface (DMI) that connects between the processor and chipset at 5 GT/s.

It is configured with 2 GB of RAM (1333 MHz PC3-10600 DDR3 SDRAM), a 250 GB hard drive, a vertically-mounted slot-loading DVD±R DL SuperDrive, and AMD Radeon HD 6750M graphics with 256 MB of dedicated GDDR5 memory.

It has a built-in FaceTime HD video camera and built-in stereo speakers underneath the vibrant 21.5″ glossy 16:9 LED-backlit TFT Active Matrix LCD (1920×1080 native) display with IPS technology.

Connectivity includes a Firewire 800 port, four USB 2.0 ports, built-in 802.11a/b/g/n Wi-Fi, Gigabit Ethernet, and an SDXC card slot as well as a single Mini DisplayPort. This does not support internal Bluetooth.

The Late 2011 iMac has the same edge-to-edge glass design and seamless all aluminum enclosure as the Mid-2010 models. Internally, the education-only Late 2011 iMac is equipped with a slower processor with half the number of cores, less standard RAM (and lower maximum RAM capacity), less VRAM, a smaller hard drive and no support for Thunderbolt or internal Bluetooth. It shipped with a less capable Apple Mouse, as well.
