All-in-one PCs combine the screen and the computer in a single unit, so a desk needs only one power cable plus a keyboard and mouse. Our range covers office desktops, home models, touchscreen terminals and Apple iMac systems, with leading brands including Lenovo, Apple, HP and ASUS.
How to choose an all-in-one PC
Screen size and touch. The 60.5 cm (23.8-inch) size is the most common in our range, with 68.6 cm (27-inch) and 61 cm (24-inch) models also available. Full HD is the usual resolution, which suits documents, email and video calls. Choose 27 inches if you work with several windows side by side, and consider a touchscreen only if customers or staff will tap the display, as in a shop or reception.
Processor and memory. Our range includes Intel Core 5, Core 7, Core Ultra 5, Core i5 and i7, and AMD Ryzen 5 processors. A Core 5 or Ryzen 5 class chip handles office software and web apps comfortably, while a Core 7 or i7 suits heavier multitasking. Look at how much memory the model supports as a maximum, since many all-in-ones allow 16 GB to 64 GB, and some models have memory that cannot be changed.
Storage. A 512 GB drive is the most frequent capacity listed in our range, with 1 TB and 2 TB versions for larger photo, video or project libraries. An SSD makes startup and file opening noticeably quicker than a hard drive, so give it priority over raw capacity. External drives can add space later.
Operating system. Most all-in-ones in our range with a listed system run Windows 11 Pro, which adds business features such as domain join and BitLocker drive encryption. Windows 11 Home is enough for home use, and a few models ship without an operating system. Apple models run macOS.
Ports and connections. Check the number of USB ports, as some models offer only one or two USB 2.0 sockets. Also look for USB-C, HDMI, Ethernet and a webcam with a privacy shutter if you plan to use it for meetings. Cable tidiness is the point of an all-in-one, so confirm the ports you need are on the machine itself.

All-in-one PC questions answered
Are all-in-one PCs good for office work?
Yes, an all-in-one PC handles office work well because it needs little desk space and has few cables. Models with an Intel Core 5 or Ryzen 5 processor, 16 GB of memory and a 512 GB SSD cover documents, spreadsheets, video calls and web apps. Business versions often add Windows 11 Pro and a built-in webcam.
Can you upgrade an all-in-one PC?
Upgrade options are more limited than on a tower PC. On many models you can change the memory or storage, but the processor and graphics are usually fixed to the motherboard. Apple iMac memory cannot be upgraded after purchase, so choose the configuration you need at the start.
What screen size is best for an all-in-one PC?
For most people a 23.8-inch screen is the best starting point, as it fits a standard desk and shows Full HD sharply. A 27-inch display gives more working room for spreadsheets, design or side-by-side windows. Sit about an arm's length away, since the screen cannot be moved separately from the computer.
How much RAM and storage do I need in an all-in-one PC?
For everyday office and home use, 16 GB of RAM and a 512 GB SSD is a sensible baseline. Choose 32 GB or more for photo editing, large spreadsheets or running several demanding programs together. Pick 1 TB or more if you keep many videos or large files locally.
