Apple iMac A1311 PC Details 

The iMac features Intel Core i5 quad core processing and the fast graphics in an all-in-one computer.
It also brings Thunderbolt I/O technology to the desktop for lightning-fast data transfer.
And the faceTime HD camera lets you make full-screen HD video calls.* All from a beautiful widescreen LED-backlit display that takes up just a sliver of your desk.
It's everything you want in a desktop. Now more powerful, more advanced, and even more incredible than before.
*FaceTime requires a FaceTime-enabled iOS device with a Wi-Fi connection or a FaceTime-enabled Mac with an Internet connection and FaceTime for Mac software (may require separate purchase). Not available in all areas.
The iMac's display offers a 1920 x 1080-pixel resolution (for native 1080p high-definition viewing), and it uses IPS technology to deliver consistent color across an ultra wide 178 degree viewing angle.
This 21.5" imac model - A1311 (MC309LL/A) - offers improved graphics, a 256GB SSD hard drive, and 8GB of installed RAM.
Other features include integrated Wireless-N Wi-Fi networking, Bluetooth connectivity, an SD card slot (compatible with SDHC and SDXC cards), one Thunderbolt port, a FireWire 800 port, and a total of four USB 2.0 ports. 
Key Features 
Quad Core Intel Processing Power
This iMac is powered by a Intel Core i5 quad core processor, which provides excellent digital media management, content creation, and 3D gaming capabilities. With Intel Turbo Boost Technology 2.0, the processor speed can increase automatically for whatever you're doing, dynamically accelerating performance to match your workload. 
Intel's Hyper-Threading Technology enables each core of your processor to work on two tasks at the same time, delivering the performance you need for smart multitasking.
And you'll enjoy a rich set of features for a stunning and seamless visual experience with no additional hardware.
The Core i5 processor also provides faster access to the installed RAM, with an integrated memory controller to connect fast 1333 MHz memory directly to the processor. 
Rear of 21.5-inch iMac 
The iMac's seamless aluminum enclosure and full range of ports, including one Thunderbolt port. 
Revolutionary Thunderbolt Technology 
Developed by Intel with collaboration from Apple, high-speed Thunderbolt I/O (input/output) technology delivers an amazing 10 gigabits per second of transfer speeds in both directions.
Built into the iMac, the Thunderbolt port allows you to connect to new Thunderbolt-compatible peripherals as well as existing USB and FireWire peripherals using simple adapters.
You'll be able to move data up to 20 times faster than using USB 2.0 and more than 12 times faster than with FireWire 800, and you can daisy-chain multiple high speed devices without using a hub.
Thunderbolt also supports DisplayPort for high resolution displays and works with existing adapters for HDMI, DVI and VGA displays. 
Bright, Colourful Display 
This 21.5" iMac features an edge-to-edge glass display that utilises LED backlighting for improved brightness and energy efficiency as well as In-Plane Switching (IPS) technology, which delivers consistent color across a wide 178-degree viewing angle.

Our Specialist view of the refurbished Apple iMac A1311

The Spec:

The Apple iMac A1311 21.5 inch refurbished All in One computer has the following spec: Released in mid 2011 with a 21.5 inch widescreen IPS LED Full HD 1920 x 1080 display that looks just amazing at almost any angle. Behind the all in one screen is an Intel Core i5 quad core (4 cores) 2.50GHz processor, 8GB RAM and a faster and sizeable 256GB Solid State Drive (SSD). All this makes up the main hardware in this iMac. For ports and networking connectivity Apple include WiFi, gigabit LAN and Bluetooth along with a HD webcam, USB 3.0 and a Thunderbolt port. It comes preinstalled with operating system MacOS 10.12 Sierra.  

The Good Bits:

Apple always manages to produce modern and stylish products. This is especially true in the case of this Mac that was first released in 2011! Unlike most of its Windows counterparts, Apple includes loads of connectivity options as standard. The internal wireless card means you can connect to a wireless network. No wireless network connection, no problem! A gigabit Ethernet connection means faster and more stable internet access. You’ll find loads of ports on the back within easy reach for peripherals, another monitor and for SD and MicroSD cards.

The Not So Good Bits:

Unlike similar Windows based AiO PC’s upgrading Apple iMacs isn’t quite as straightforward. The RAM isn’t the tricky bit; if you want to upgrade the hard drive it requires specialist tools to remove the screen. So it’s not impossible but it isn’t straightforward.

The Design:

What’s not to love about how this iMac looks? Apple did set the benchmark for design in all in one computers.  Its slim profile coupled with the slim bezel and brushed aluminium, it’s a work of art. Apple really knows how to nail the design aspect and at the same time remember to include plenty of ports and incorporate a simple but effective cable tidy in the stand. 10/10 from us.


There isn’t an environment we can’t see this pc in, whether that is in a school or college, on a reception desk or design agency or even at home as an affordable Apple iMac option.
