Choosing Your RAM and Storage Configuration

Every unit is available with 8GB, 16GB, 32GB or 64GB of RAM and a 256GB, 512GB, 1TB or 2TB SSD, so you can match the specification to how you’ll use it. 8GB is comfortable for everyday browsing, email, video calls and light photo editing; 16GB or 32GB is worth the upgrade if you regularly run several applications side by side, work with large photo or video libraries, or keep many browser tabs open; 64GB suits demanding creative or professional workloads. On storage, 256GB or 512GB suits buyers who lean on cloud storage and keep a modest local footprint, while 1TB or 2TB gives substantial headroom for local photo, video or document archives without needing an external drive. Whichever combination you choose, the processor and graphics are identical, so performance for everyday tasks doesn’t change.

5K Retina Display for Detail-Critical Work

The 27″ 5K Retina display packs over 14.7 million pixels into a wide-gamut panel, giving exceptional sharpness and colour accuracy for photo editing, design work and general everyday use. Combined with the dedicated AMD Radeon Pro 570X graphics, the iMac 27″ comfortably handles photo editing, multiple external displays and everyday creative tasks well beyond what integrated graphics alone can offer.

Thunderbolt 3 Connectivity and Storage

Two Thunderbolt 3 (USB-C) ports support fast external storage, docking and additional display output, while four USB 3.0 ports cover everyday peripherals. An SDXC card slot is built in for quick photo transfers from a camera, and Gigabit Ethernet gives stable wired networking for larger file transfers. Every configuration uses a genuine SSD rather than the slower Fusion Drive this model was also offered with, so load and save times are consistently fast regardless of which storage size you choose.

An All-in-One Desktop for the Home or Office

With the wireless keyboard and mouse included, the iMac 27″ 5K is ready to use straight out of the box, without the cable clutter of a separate tower and monitor. Its all-in-one design and large 5K screen make it a strong choice for a dedicated home office setup, a family computer, or a secondary desktop workstation.

Real-World Everyday Performance

For browsing, email, video calls, Office and everyday creative work, the 6-core i5 combined with dedicated AMD graphics performs comfortably beyond what an entry-level all-in-one or laptop can offer at this price. Boot times and application loading are fast thanks to SSD storage across every configuration, so the day-to-day experience feels closer to a current machine than a 2019 spec sheet might suggest, particularly for buyers coming from an older HDD-based Mac or PC.

Refurbished vs New at This Price Point

Apple no longer sells a 27-inch iMac new — the line was discontinued, and the closest current equivalent is a smaller 24-inch Apple Silicon iMac at a significantly higher price with less screen real estate. Buying this certified refurbished 27″ 5K model gets you a genuinely large, high-resolution all-in-one at a fraction of what any comparable new Apple desktop costs today, backed by our 30-point inspection and 14-month warranty.

Who Is This For?

This iMac 27″ 5K is a strong fit for buyers who want a large, high-resolution all-in-one display for everyday computing, light-to-moderate photo editing, or home and family use, and for anyone who wants desktop-class performance without a separate monitor and tower.

Not ideal for: high-end gaming. For home office, photo editing and everyday macOS use, the iMac 27-inch 5K is a strong fit.

Typical Use Cases

This configuration suits home and family computing, everyday office and admin work, web browsing and video calls, and light-to-moderate photo editing thanks to the 5K display and dedicated graphics. It also works well as a secondary desktop for a home office alongside a primary laptop, or as a shared family computer that benefits from a large, comfortable screen.
