Best All In One Desktop PCs to buy in 2021

- ADVERTISEMENT -

A buying guide with ranking on the best all-in-one PCs for home and professional use to switch from cheap to top-of-the-range models.

Do you need to replace your old PC? An All In One could be a good choice- more expensive certainly, but less bulky as they combine case and monitor in a single element.

Unlike traditional desktops, the best All in One PCs have screens integrated into the computer chassis. You’ll often find a mix of desktop and laptop components in an All-in-one, and while that makes upgrading more difficult, this approach definitely has its benefits.

Which all in one desktop PC to choose

One of the biggest advantages of the best All in One PCs is that they not only save space but are also cheaper to run because they only consume 60 Watts against an average of 160 Watts for a desktop with a monitor.

Plus, due to the smaller amount of cables (just one power cord), you won’t be tripping over annoying cables.

This makes the best all-in-one PCs a perfect choice for those who work in an office and want to keep a clean and professional workspace. It’s no coincidence that all-in-one PCs are favored by creative professionals, especially the Surface Studio 2 or iMac Pro.

The only disadvantages of the All-In-One that I would like to point out are:

  • The lower power compared to the desktop of the same price range.
  • The inability to update the CPU or graphics card.

In conclusion, the All In One has a refined design with a wireless keyboard and mouse, high speed, small footprint, low energy consumption, but little possibility of updating the internal components. Those who buy this product enjoy above-average silence and trouble-free installation- just plug in the power cord and turn on the PC.

However, it’s still very powerful for meeting the needs of creative professionals who don’t like expensive Apple computers.

Additionally, the Lenovo Yoga A940 has a few tricks up its sleeve, including 100% Adobe RGB and Dolby Vision support, a Dolby Atmos speaker set, a more generous port offering than Apple iMacs, and a stylus included in the box.
