One owner iMac in fantastic shape. Mid-tier model with upgraded processor, RAM, fusion drive and discrete video card. The 4K screen is flawless, and really impressive. This machine still performs really well, and can be upgraded to a full SSD storage, and additional RAM. Specs: iMac (Retina 4K, 21.5 2017) Processor: 3.4GHz Quad-Core Intel Core i5 Memory: 16GB 2400 MHz DDR4 Fusion Drive (Hybrid NVME/HD) Graphics: Radeon Pro 460 4GB Naturally has all of the other features, WiFi 80211.AC, Bluetooth, Thunderbolt 3 ports, USB 3.1 ports, Gigabit ethernet, SD card reader etc. I have the original box and packaging, The Magic Keyboard 2 and Magic Mouse 2. I will include a Satechi USB3.1 hub/stand into the bargain.
