Choosing an all-in-one PC: a practical buying guide for home, study and work

An all-in-one PC combines the computer and screen in a single unit. This saves space and reduces the number of cables on your desk. However, not every desktop PC with a built-in screen is suited to the same tasks. A model for email and word processing needs different specifications from one for a business workstation, photo editing or intensive multitasking.

As a Joybuy Product Recommendation Officer, I focus on specifications you can verify. This helps you avoid giving more weight to an attractive design or a high clock speed than to the components you’ll use every day.

Three common pitfalls when choosing an all-in-one PC

1. Focusing only on the processor

A brand name such as Intel Core or Apple M3 doesn’t tell you everything. Also look at the number of cores, RAM, storage and integrated graphics. An all-in-one computer with 8 GB RAM may be suitable for basic office software, but 16 GB is more practical if you use lots of browser tabs, make video calls and work with large files.

Check whether the memory can be upgraded, too. Some models have integrated memory that can’t be replaced later. For example, the Acer Aspire C24-A has 16 GB LPDDR5X memory, which the product specifications state cannot be upgraded.

2. Mistaking a large screen for a sharp one

A larger screen isn’t automatically sharper. A 24-inch all-in-one PC with Full HD has a different pixel density from a 27-inch model with QHD. For text, spreadsheets and image editing, resolution, panel type and brightness matter more than screen size alone.

A 23.8-inch all-in-one PC with an IPS panel and Full HD is often enough for working from home. If you spend a lot of time working with images, video or multiple windows, you may benefit from QHD or a higher resolution.

3. Overlooking ports and accessories

Check in advance that you have enough USB ports, a headphone socket and an HDMI or DisplayPort connection. Pay attention to how the HDMI port works, too. According to the product information, the HDMI 2.1 port on the Lenovo Yoga AIO 27IAH10 can be used as an input, so you can use the screen with another computer.

Also check what’s included in the box. Several MSI models are listed as no longer coming with a charger as standard, which must be bought separately. This affects the total cost.

Which specifications matter most?

RAM and storage

For browsing, word processing, streaming and video calls, 8 GB RAM is a useful starting point. For more intensive multitasking, creative software or extended business use, 16 GB RAM is a more sensible starting point. Storage determines how many files and programmes you can keep on your computer:

  • 256 GB SSD: suitable for basic use if you keep lots of files in the cloud.
  • 512 GB SSD: a practical middle ground for study, office work and home use.
  • 1 TB SSD: useful for large photo libraries, projects and files stored locally.

An SSD usually opens programmes faster than a traditional hard drive. Check whether the storage can be upgraded, as this varies by model.

Screen size, resolution and panel

A 23.8-inch or 24-inch IPS screen fits well on an average UK desk. Full HD with 1920 × 1080 pixels is suitable for everyday tasks. A 27-inch QHD screen with 2560 × 1440 pixels gives you more room to work with spreadsheets, design software and multiple windows.

Also look out for:

  • Matt or anti-glare coating: can reduce distracting reflections.
  • Brightness: measured in nits; important in bright rooms.
  • Refresh rate: 60 Hz is enough for office work, while 120 Hz can make movement look smoother.
  • Touchscreen: only worthwhile if you’ll actually use the touch controls.

Claims about viewing comfort or eye strain should be treated as product specifications, not medical guarantees. The Lenovo Yoga AIO is listed as having Eyesafe Certified 2.0 and TÜV Rheinland technology; these are features mentioned in the brand’s product information.

Operating system and connectivity

A Windows 11 Pro PC supports business features such as management within a company environment. Windows 11 Home is often enough for home users and students. An Apple iMac runs macOS, so check in advance that the programmes you need are available for that system.

Wi-Fi 6 and Wi-Fi 6E are common options for wireless connectivity. Wi-Fi 7 is available on newer compact systems, but you’ll only benefit if your router supports it, too. An Ethernet port is still useful for a stable connection at a fixed workstation.

Frequently asked questions about all-in-one PCs

Is an all-in-one PC suitable for working from home?

Yes, if the model has enough RAM, an SSD, a built-in webcam and the right connections. For standard office software, video calls and browsing, 8 GB RAM is often enough. If you use lots of programmes at once, 16 GB is more comfortable.

How long does an all-in-one computer last?

Its lifespan depends on the components, software updates and how you use it. A model with a faster processor, plenty of RAM and enough SSD storage will generally remain practical for longer. Also check whether the RAM or storage can be replaced later. Many of the models mentioned come with a minimum two-year legal guarantee in the EU, but always check the specific product listing.

Does an all-in-one PC use a lot of power?

An all-in-one PC usually has a single integrated power supply for the computer and screen. Power consumption varies depending on the processor, screen brightness and how intensively you use it. An energy-efficient office computer usually uses less power than a system running demanding graphics tasks continuously. Turn off the screen and computer when you won’t be using them for a while.
