All-in-One PC Buying Guide
Editor's Note
Choose memory and screen size first, because both are hard or impossible to change later on an all-in-one. 8GB of memory handles browsing, email and video calls; 16GB keeps a home office machine responsive with many tabs and apps open. Every model here uses graphics built into the processor, so none is a gaming computer. If you want to game or upgrade parts later, look at our desktop PCs instead.

Editor's Pick
It pairs a 27-inch Full HD screen with 16GB of DDR5 memory, a 512GB SSD and Wi-Fi 6E, which is the right balance for a family or home office computer that should last several years. It also has one of the strongest buyer ratings in the category, across more than a hundred ratings, and comes with a keyboard and mouse.
Budget
21.5 to 24-inch all-in-ones from HP and Lenovo for browsing, email, documents and video calls
Mid-Range
27-inch all-in-ones with 16GB of memory, such as the Dell 27, for a home office
Premium
AI-ready all-in-ones such as the HP OmniStudio 27 with an AMD Ryzen AI 7 processor
Common Mistakes to Avoid
- ⚠Buying 8GB of memory for a computer you plan to keep for years: memory is hard to upgrade in an all-in-one
- ⚠Expecting to play current games: all-in-ones use graphics built into the processor
- ⚠Assuming the screen works as a monitor for a laptop or console: most budget all-in-ones have HDMI out but no HDMI in

Frequently Asked Questions
Is an all-in-one computer better than a desktop tower?
An all-in-one is better if desk space and tidiness matter most: the screen, computer, speakers and webcam share one unit and one power cable. A tower is better if you want to upgrade parts later or add a graphics card, because an all-in-one's memory, storage and display are hard or impossible to replace. If the screen fails, the whole computer goes in for repair.
How much RAM does an all-in-one PC need?
8GB covers browsing, email, documents and video calls. Choose 16GB if you keep many browser tabs open, edit photos or run several apps at once. Memory is harder to upgrade in an all-in-one than in a tower, so buy the amount you will need for the life of the computer.
Can I use an all-in-one PC as a monitor?
Only if it has an HDMI input. Most budget all-in-ones have an HDMI output for a second screen but no input, so a laptop or game console cannot use their display. Check the listing for the words "HDMI in" before you buy for this reason.
Are all-in-one computers good for gaming?
Not for current games. Every all-in-one in our list uses graphics built into the processor (Intel graphics or AMD Radeon 840M), which handle older and lighter games at low settings. For modern games, a gaming desktop with a dedicated graphics card such as an RTX 5060 Ti is the better choice.
What screen size should I choose for an all-in-one?
A 21.5 to 24-inch model fits a kitchen counter, a reception desk or a child's homework desk. A 27-inch screen is easier for side-by-side windows in a home office. All four models in our list have Full HD (1920 x 1080) screens, which look slightly less sharp on a 27-inch panel than on a 24-inch one.
