Apple iMac 21.5” All-in-One Desktop Computer (Refurbished) (Mid 2011)

The Apple iMac streamlines the traditional desktop computer setup by fitting all of its powerful hardware into the same housing as its sleek Full HD monitor, eliminating the need for a bulky tower. This saves space on your desktop for peripherals such as a scanner or printer.

Work and Play in Full High Definition

From full-length films to funny video clips, virtually everything you see on this computer’s display renders in crisp, lifelike detail. Its 1080p Full HD resolution is the same as that of many big-screen HDTVs, fitting the same amount of pixels—just more than 2 million—into a smaller space, so even everyday websites appear sharp and realistic. In addition to heightening the impact of streaming shows, video games, and other visual media, Full HD resolution makes photos pop and can help you get a more accurate look at potential online purchases.

Video Chat with Anyone, Anywhere

A built-in webcam can make it feel like people miles away are in the room with you, helping you connect more clearly than with a phone call or email. Collaborate with colleagues in other offices, listen as your niece or nephew rapturously explains their finger painting, or laugh every time your friend’s cat walks across their keyboard.

Do More with High-Speed Thunderbolt

Whether you’re uploading 4K video or backing up your entire photo library, Thunderbolt connectivity helps you move files to and from your computer smoothly. When connected to compatible devices, a Thunderbolt port supports data transfer speeds of up to 10GB/s—double the speed of USB 3.0—in both directions. With that kind of bandwidth, you can move large files and connect an external monitor, all from a single port.

About Apple

From the start, Steve Jobs was enthralled with not only the novelty of technology but also its design. When speaking about the Apple computer, he said it was “going to be insanely beautiful.” Over the years, Apple’s products have worked to fuse innovative technology with almost artful design. The iMac stunned the world with its colorful plastic shells, which the New York Times said “more closely resemble a pack of Life Savers than a new computer line.” The glossy white iPod—no bigger than a deck of playing cards—could hold an entire library of music. Time Magazine named the iPhone the Invention of the Year for its stunning design and, uniquely, because of the promise it held for even better products in the future. With each new item they launch, Apple works to shape the way future societies communicate, learn, and dance when they’re alone.

After receiving it, the serial number showed that it was a 2011 model, ancient by computer standards. Furthermore, the fan noise was too loud - completely unacceptable. I own several other iMacs and none of them had this problem. I called Apple Support to see if there was a method to quiet down the fan, but all efforts failed.
