My wife and I bought this monstrous iMac back in 2011 and used it as our home base computer for a good 8 years. It still looks virtually brand new and runs better now than it did when we bought it since we upgraded the RAM from 4GB to 16GB and the hard drive to a 1TB solid state drive. The only reason we're selling is we now have 2 more powerful laptops and this has sat dormant since we got them, but it's still plenty powerful.
Fresh install of High Sierra, the last OS that Apple supports for it. I *do not* have a keyboard or mouse I can sell with it, though. Luckily, 3rd party options are inexpensive on Amazon.
