Apple killed off the 27-inch iMac in 2022, leaving a gaping hole for anyone wanting a large-screen all-in-one Mac. With the 24-inch M1 iMac feeling cramped and no 27-inch replacement in sight, many buyers are turning to refurbished Intel models. But with options spanning eight years of releases, from a £130 2012 model to a £499 2019 variant, which ones actually make sense in 2026?

The brutal truth: most don't. But a couple represent genuine value if you understand their limitations.

The 27-inch iMac Landscape: What's Actually Available

The refurbished market offers five distinct generations, each with different strengths and fatal flaws. Here's what you're looking at:

❌ 2012 iMac 27" (Grade A, £130)

This machine is 14 years old. Yes, £130 seems tempting, but you're buying a computer that can't run macOS beyond Monterey, struggles with modern web browsing, and likely has a failing hard drive. The third-generation Intel Core processors are painfully slow by 2026 standards, and 8GB of RAM feels restrictive even for basic tasks.

The 5K display revolution hadn't happened yet, so you're stuck with 2560x1440 resolution. For £20 less than our 21.5" 2015 model, it might seem like a bargain, but it's false economy.

❌ 2014 iMac 27" (Grade A, £250)

This was the first 5K iMac, and that Retina display still looks spectacular. The problem is everything else. Fourth-generation Intel processors are marginally better than 2012, but still wheeze under modern macOS. Most crucially, many 2014 models shipped with fusion drives that are now failing catastrophically.

At £250, you're paying £120 more than the 2012 model for essentially the same performance with a better screen. The display alone doesn't justify that premium when the underlying machine is still fundamentally outdated.

❌ 2015 iMac 27" (Grade C, £150)

The Grade C rating tells you everything. These machines have visible wear, potential display issues, or other cosmetic problems. Given that the internals are barely improved over 2014 models, you're essentially gambling £150 on a machine that might have serious issues beyond just scratches.

For £20 more, you could buy our refurbished iMac 27" 2019 – though as we'll see, even that has problems.

❌ 2017 iMac 27" (Grade B, £280)

Here's where things get interesting, then disappointing. The 2017 refresh brought proper SSD storage and significantly faster processors. Seventh-generation Intel Core chips can actually handle macOS Sequoia respectably. The problem is that £280 price point.

You're now approaching the cost of our Grade A Microsoft Surface Laptop 3 at £299, which offers similar performance in a modern, portable package. The 2017 iMac isn't bad, but it's poor value.

✅ 2019 iMac 27" (Grade A, £499)

This is the only 27-inch iMac that makes genuine sense in 2026, but with caveats. The ninth-generation Intel processors are genuinely capable, the 5K display remains gorgeous, and build quality is excellent. You get modern connectivity, proper SSD storage, and macOS support through 2027 at minimum.

The catch? £499 is serious money. You could buy our refurbished MacBook Air M2 at £600 and get dramatically better performance, though you'd lose the integrated display.

The Display Dilemma: What About Alternatives?

Here's where the maths gets interesting. Instead of buying a 2017 iMac for £280, consider this combination:

Total: £448 – that's £32 less than the 2019 iMac, and you get a modular setup. The Mac Mini's performance roughly matches the 2015-2017 iMac range, but you can upgrade it separately when needed.

Alternatively, pair any modern laptop with our HP displays starting at £60. A Surface Laptop 3 (£299) plus HP E231 monitor (£74) gives you £373 total cost with better flexibility.

Real-World Performance: What to Expect

I've tested 2015-2019 iMacs extensively, and here's the reality:

2015-2017 models: Fine for web browsing, office work, and light photo editing. Video editing is painful, modern games are impossible, and you'll notice lag in demanding applications. Safari with 20+ tabs will cause beach balls.

2019 model: Genuinely usable for most tasks including 4K video editing, though render times are lengthy. Gaming remains limited, but photo editing in Lightroom is smooth. This machine will serve you well for 2-3 years minimum.

The Honest Verdict

Buy the 2019 iMac 27" at £499 if you specifically need macOS, want an all-in-one solution, and value that stunning 5K display above all else. It's expensive but genuinely capable.

Avoid everything else. The 2012-2017 models are false economy – too slow for modern demands despite tempting prices.

For most buyers, better value lies elsewhere. The 24" M1 iMac at £699 offers dramatically better performance for £200 more. If you need Windows, the Surface Laptop 3 at £299 plus a decent monitor gives you more flexibility and similar total cost to the older iMacs.

The 27-inch iMac's death in 2022 was inevitable – these Intel machines were already feeling dated then. Unless you have specific macOS requirements and a genuine need for that 5K display, your money goes further elsewhere.

Buyer Area Ltd has been trading since 2011 (Companies House No. 07830466), offering 12-month warranties and free UK delivery on all models. But even with that security, most 27-inch iMacs represent expensive nostalgia rather than smart buying.
