All-in-One with 21.5-inch 4K Display

The Apple iMac MK452LL/A is a refurbished all-in-one desktop that integrates a 21.5-inch Retina 4K display, an Intel Core i5-5675R quad-core processor at 3.1 GHz, 8 GB of DDR3 memory and a 1 TB SATA hard drive spinning at 5400 RPM. It ships with OS X 10.11 El Capitan, a wired keyboard and a wired mouse. The display delivers a 4096 x 2304 resolution for 9.4 million pixels, which is 4.5 times more than a 1080p panel, and uses a P3-based colour gamut 25% larger than sRGB.

Suits office and home users who want

Buyers who need a single-cable workstation for documents, web browsing, email and media playback will find the integrated screen, keyboard and mouse convenient. The 8 GB memory and mechanical drive limit heavy multitasking, large creative projects or modern macOS upgrades, so professionals who rely on fast storage or more RAM should look elsewhere. The Scratch and Dent classification means visible cosmetic blemishes are present but the screen, keyboard and trackpad are free of functional damage.

1 TB hard drive and 8 GB RAM handle everyday

The 1 TB capacity stores a large photo library, documents and backups with room to spare, while the 5400 RPM mechanism provides steady sequential throughput for media files. The 8 GB DDR3 memory keeps several browser tabs, office apps and background services responsive. Performance runs out when editing 4K video, running virtual machines or opening very large datasets, where the mechanical drive latency and memory ceiling become bottlenecks.
