Best all-in-one PCs that take up little space

All in one PC

The space available on our desk does not always allow us to have a powerful PC and a neat monitor, forcing us to choose desktops much smaller than those we wanted to place on it. If we care a lot about aesthetics and want a very tidy desk (especially in the workplace), we advise you to focus with your eyes closed on All-in-One PCs, i.e. computers that integrate all the most important components within the monitor itself , so you can have a complete computer taking up very little space on your desk.

In this guide we will show you the best All-In-One PCs to choose from, not without first taking a look at the technical features that these special computers they must have in order to keep up with the times and be effective for at least 3-4 years, without having to think about how to update them and how to increase memory and RAM (which is considerably more difficult than a traditional PC).

Best All-In-One PCs

All-In-One computers are really beautiful to look at and comfortable to use on an office desk, but not all models are capable of effectively replace a traditional desktop PC. To avoid rip-offs or too many old models we recommend first reading the technical characteristics that these computers must have and, only then, dive into the buying guide, so as to have a good reference even in case we decide to buy a computer in a shopping center or in an electronics store.

Technical features

A good All-in-One PC (also called AIO) must have the following technical characteristics to be at the forefront and not immediately feel the weight of the years:

  • Monitor: in the end we are still talking about a PC embedded inside a monitor, so we must first of all make sure that the screen is good before seeing everything else. The cheaper AIOs have a diameter of 22 or 24 inches, while the top models go for 27 inches, which are accompanied by a FullHD or 5K resolution (Apple's special resolution), anti-glare screen, IPS type panel and high dynamic contrast. so as to be able to faithfully reproduce shadows, lights and colors.
  • Main components: inside the AIO we find a small motherboard in which there are CPU, RAM and internal memory (storage disk). To be able to keep up with the times, let's make sure that there is a latest generation AMD or Intel processor, at least 8 GB of DDR4 RAM and a fast SSD or M.2 with at least 256 GB of internal memory. We avoid models with mechanical disks: they have now gone out of order and are too slow for this type of computer.
  • Sockets and connections: in order not to miss anything, make sure that on the chosen AIO PC there is a dual band Wi-Fi module and a connection module for Bluetooth, so that we can connect wireless devices and connect to any wireless network. On the back we will also find at least 3 fast USB ports (3.0 or later), an Ethernet port for wired Internet connection and various audio / video outputs (for headphones, speakers or to connect other monitors).
  • Audio and video components: if we really want to minimize the size of the AIOs, we only choose models that integrate the webcam in the upper part of the monitor (as on laptops) and that have audio speakers on the lower edge, sufficient to reproduce the sounds and audio of the video calls or videoconferencing.
  • Input devices: to control the AIOs we advise you to focus on the wireless mouse and keyboard, so as to minimize the clutter of wires (in fact we will only have the power supply wire!).

Speaking of wireless mouse and keyboard: if they are not included in the AIO PC box, we can get a complete kit by reading our tips in the guides Wired or wireless mouse: which is best? is Types of PC keyboard: wifi, ergonomic and backlit.

All-In-One computers are the ideal choice for a doctor's or architect's elegant office, but they are also well suited for home use when we have very little desk space, as everything is integrated within the monitor. Obviously we must always take into consideration the shortcomings of this type of solution: low future expansion capacity (often only RAM and SSD are interchangeable) and a power often not up to par with traditional desktop PCs, even when compared with computers of the same price.

If we want to create our desktop PC by choosing the components and spending the same figures seen above, we suggest you read our guides How to choose the parts of the new computer to assemble is High-performance 600 Euro assembled PC with high performance. At the price of the iMac we can instead assemble the most powerful desktop computer, as seen in our article Most Powerful PC Ever – Better Hardware Parts Today.
