It is the only S tier product on our all-in-one computers board, ranked across independent research runs over current expert reviews, and reviewers single out its processor and Retina display as the strongest of any all-in-one. The A tier runner-up is the Lenovo Yoga AIO 27, a premium Windows machine with an Intel Core Ultra 7 and a quiet chassis. If you need Windows on a tighter budget, pick the Dell 24 All-In-One, a well-rounded B tier choice. If you want a compact desk footprint with strong fan-noise control, pick the MSI Modern AM271P 11M. Avoid the HP OmniStudio X 31.5 AIO, the HP Pavilion 24 All-In-One, the Lenovo ThinkCentre AIO and the Dell Inspiron 7730 (AIO) - older 2023 model, all in D tier. ## Ranking | Rank | Product | Brand | Tier | LP | Outlets | Verdict | Page | | --- | --- | --- | --- | --- | --- | --- | --- | | 1 | Apple iMac 24-inch M4 | Apple | S | 1027 | 49 | The consistent top recommendation across multiple sources establishes it as the leading choice for performance and display quality. | https://stierproducts.com/products/apple-imac-24-inch-m4 | | 2 | Lenovo Yoga AIO 27 | Lenovo | A | 729 | 10 | Its inclusion in both TechAura’s list and HTECK's video demonstrates broad appeal and positive community perception. | https://stierproducts.com/products/lenovo-yoga-aio-27 | | 3 | MSI Modern AM271P 11M | MSI | B | 601 | 4 | A compact yet powerful option that uses the latest Intel Core Ultra 7, with a sturdy chassis and excellent fan-noise control for its size. | https://stierproducts.com/products/msi-modern-am271p-11m | | 4 | Dell 24 All-In-One | Dell | B | 552 | 25 | Solid, well-rounded choice with good specs, though slightly less powerful than the EC24250 variant. | https://stierproducts.com/products/dell-24-all-in-one | | 5 | Dell Inspiron 7730 (AIO) | Dell | C | 390 | 24 | Older 2023 model - The Reddit user's rejection of this model suggests it falls short compared to newer options. | https://stierproducts.com/products/dell-inspiron-7730-aio | | 6 | HP OmniStudio X 31.5 AIO | HP | D | 348 | 3 | Over-hyped for its 4K display, but reviews point to sluggish performance and a cramped internal layout that limits upgradeability; better to choose a tower+monitor combo. | https://stierproducts.com/products/hp-omnistudio-x-31-5-aio | | 7 | Dell Inspiron 7730 (AIO) - older 2023 model | Dell | D | 330 | 1 | The 12th-gen Intel i7 and integrated graphics are powerful; Dell’s support is reliable.

An all-in-one computer is a desktop PC built into the back of its monitor, so the screen, processor, memory, storage and speakers sit in one unit. You plug in power, a keyboard and a mouse and it is ready. It takes less desk space than a tower and monitor and has far fewer cables. Mini PCs and towers are not all-in-ones, because the display is separate. ### Are all-in-one computers good? Yes, for most home and office use. The best ones match a good laptop or a mid-range tower for everyday work, and our board's top pick, the Apple iMac 24-inch M4, is praised for both performance and display quality. The trade-off is upgradeability and cooling: the parts are packed behind the screen, so they are harder to replace and run warmer under sustained load. On our board the HP OmniStudio X 31.5 AIO shows the downside, with reviews pointing to sluggish performance and a cramped internal layout. ### Should I buy an all-in-one or a desktop tower and monitor? Buy an all-in-one if you want a clean desk, minimal cables and a machine you will not open up. Buy a tower and monitor if you want to upgrade the graphics card, memory or storage later, or if you need sustained heavy performance. A tower also lets you keep the monitor when the PC is replaced. Our board's research on the HP OmniStudio X 31.5 AIO reached the same conclusion for that product, recommending a tower and monitor instead. ### What screen size should an all-in-one computer have? 24 inches suits a small desk and general use, 27 inches is the sweet spot for photo work, spreadsheets and watching video, and 31.5 inches or larger is for people who want a single big canvas. On our board the Apple iMac 24-inch M4 holds the top spot at 24 inches, which shows size is not what decides quality. The Lenovo Yoga AIO 27, the MSI Modern AM271P 11M and the Dell Inspiron 7730 (AIO) are 27-inch options. Check the resolution too: a 27-inch screen should be at least QHD so text stays sharp. ### Which brand makes the most reliable all-in-one computer? Apple leads our board, and reviewers note an industry-leading 10-year warranty behind the Apple iMac 24-inch M4. Among Windows makers, Dell's support is described as reliable across both Dell Inspiron 7730 entries, and the HP Pavilion 24 All-In-One is credited with high reliability and a dependable 5-year warranty even though it ranks in D tier for its overall value. Lenovo is mixed: the Lenovo Yoga AIO 27 is A tier, while the Lenovo ThinkCentre AIO is marked down for mixed firmware support. ### How long does an all-in-one computer last? Plan on five to seven years of useful life for a good one. Because you usually cannot upgrade the processor or graphics, the chip you buy is the chip you keep, so buy more performance than you need today. Memory and storage are sometimes replaceable, which helps at the three to four year mark. On our board the older Dell Inspiron 7730 (AIO) - older 2023 model shows how quickly a previous-year build can fall behind newer options on value. ### Can you upgrade an all-in-one computer? Usually only the memory and the storage drive, and on some models not even those. The processor and graphics are soldered or locked to the board in nearly every all-in-one. Apple's iMac, including the Apple iMac 24-inch M4, has no user-upgradeable parts at all, so pick your memory and storage at purchase. Reviews of the HP OmniStudio X 31.5 AIO on our board call out its cramped internal layout as a specific limit on upgrades. ### Is an all-in-one computer good for gaming? Only for light and mid-range gaming. Most all-in-ones use laptop-class chips and integrated or mobile graphics, and the thin chassis limits cooling under long sessions. On our board the Dell Inspiron 7730 (AIO) pairs an Intel Core i7-13700H with an RTX 4060, the strongest gaming hardware listed, but it sits in C tier because newer models offer better value. The Lenovo ThinkCentre AIO is credited with gaming capability at an affordable level but reviewers found its overall performance underwhelming. Serious gamers should buy a tower. ### Mac or Windows all-in-one? If you do not need Windows-only software, the Apple iMac 24-inch M4 is the clear choice on our board and the only S tier product. If you need Windows, the Lenovo Yoga AIO 27 is the best of the Windows machines in A tier, with a powerful Intel Core Ultra 7 and a premium build. The Dell 24 All-In-One is the well-rounded Windows option further down in B tier. ### What should you avoid when buying an all-in-one computer? Avoid last year's model sold at this year's price: the Dell Inspiron 7730 (AIO) - older 2023 model and the HP Pavilion 24 All-In-One are both marked down on our board for specs that do not justify their cost. Avoid paying for a big 4K screen before checking the chip behind it, which is the trap reviewers describe with the HP OmniStudio X 31.5 AIO. Avoid the minimum memory configuration, because you may never be able to add more. Avoid a model with no published reviews, since you cannot check its performance claims. ### Who should not buy an all-in-one computer? Anyone who wants to upgrade parts, run demanding games, edit long video projects or keep the same monitor through several PCs should buy a tower and a separate monitor instead. People who need to move their computer between rooms or work on the go are better off with a laptop and a dock. If you just want a tidy desk for browsing, office work and calls, an all-in-one is the right shape, and the Apple iMac 24-inch M4 is where our board says to start. ## Tier meanings - S: Exceptional. Finishes top run after run; capped at 3 slots per category. - A: Excellent. Strongly recommended, beaten only by the very best. - B: Good. A solid choice with real caveats worth knowing. - C: Fair. Acceptable in the right situation, outclassed at its price. - D: Weak. Hard to recommend when better options cost similar money. - F: Avoid. The evidence points you elsewhere. ## How to read this - Each category is researched in four independent runs, one per lens (expert consensus, value, reliability, community pulse). Every run ranks a board of candidates that deliberately includes products buyers cross-shop but should avoid. Placements score on a ranked ladder (LP), and tiers are derived from LP, so no tier is ever assigned by hand. - LP is the product's points on this category's ladder. It is comparable within a category and not across categories. - Outlets is how many distinct outlets are cited for that placement. The per-product page lists each citation, and shows which of their links were fetched and confirmed before publishing. - Nothing is hidden: every product the research placed is on this board.
