Best for Business

Dell OptiPlex 3280 All-in-One Desktop

Dell OptiPlex 3280 All-in-One Computer


What We Like
  • Ergonomic stand

  • Robust design

  • Anti-glare display

  • Reliable bundled peripherals

What We Don't Like
  • Lackluster performance for the price

  • Small display size

The OptiPlex 3280 is great for businesses buying all-in-one desktops. It has several height-adjustable stand options and various affordable peripherals (computer accessories) that do the job without standing out on a desk. Companies that use smart cards for authentication or other purposes can opt for a smart card keyboard.

Support for external accessories is excellent too. This all-in-one supports DisplayPort for connecting an external monitor, various USB ports, including USB 3.0 and USB-C, for other devices like keyboards, and an SD card reader for viewing digital media or transferring files. Connectivity options include Wi-Fi 6 and Bluetooth 5, and the OptiPlex supports wired Ethernet also.

The OptiPlex 3280 has a small 21.5-inch display, but other models offer up to 27 inches. All OptiPlex models come standard with an anti-glare display that significantly reduces reflections, making the display usable in bright environments like an open office or retail store. While the 3280 is rather expensive for what it offers, the wide range of business-oriented features not found on most competitors' models justifies the price.

Best for Home Users

Dell Inspiron 27 7000 All-in-One

Dell Inspiron 27 7000 All-in-One Desktop


What We Like
  • Strong performance

  • Attractive slim-bezel display

  • Approachable pricing

  • Lots of connectivity

What We Don't Like
  • Large, wide stand

  • Graphics could be better

The Dell Inspiron 27 7000 is a solid pick for any home. Base models have a reasonably quick processor and good graphics, but even upgraded options aren't ideal for gamers. Everyone else will be satisfied with the performance and excellent connectivity. Every Inspiron 27 7000 packs multiple USB ports, including USB 2.0 and 3.0 and USB Type-C, HDMI input and output ports, and an SD card reader. Wi-Fi 6 and Bluetooth 5.1 are supported, as well.

If you want to add an attractive all-in-one to your home, the 7000 has thin display bezels (borders) for a more modern look than many competitors, including Apple's 27-inch iMac. The stand is large, though, so measure your desk before purchasing.

Dell throws a wireless keyboard and mouse with every Inspiron 27 7000 all-in-one PC. They're pretty decent, and most people won't see a reason to replace them. It's hard to beat this Dell for the price. It's the right size, has the proper hardware, and looks good on a desk.

What to Look for When Buying AIOs

Screen Size

Buying an all-in-one with the right display size is essential because you can’t replace or alter it after purchase. Twenty-four inches is a good fit for users who aren’t too demanding, while 27 inches is more enjoyable and worth paying a premium. Thirty-two-inch all-in-ones are rare but do provide an outstanding visual experience. The only downside is their sheer size; they’re as large as a small television and can be challenging to place on a desk.


All-in-ones can be hard to upgrade down the line, so paying close attention to the specs is even more critical. Things to pay attention to include the processor, RAM, storage, and graphics card (if applicable). High-end graphics are useful for 3D games, video and photo editing, 3D modeling, and other demanding applications. A solid-state drive (SSD) paired with a hard disk is good enough, but avoid models that only offer a hard disk for storage.

Pay close attention to connectivity when buying an all-in-one. The ports available on all-in-ones vary significantly between models. Some offer nearly as many ports as a full-sized desktop tower, while others have fewer ports than a thin-and-light laptop. Expanding connectivity with a USB hub is always possible, but having the ports you need from the start is better.

  • What is an all-in-one PC?

    An all-in-one (AIO) PC is a computer where the monitor and tower are in the same unit. The monitor houses the motherboard, RAM, and other components that make the computer a computer. This design concept helps to save space, which is perfect for homes and offices on the smaller side.

  • Can you use an all-in-one PC as a monitor for another computer?

    Most all-in-one computers don't support this. Usually, all HDMI, USB-C, or DisplayPort connections on an AIO computer are display output ports. These ports allow you to connect an all-in-one to another monitor for a multi-screen setup, but you cannot use an AIO PC as a secondary monitor for another system. There are exceptions, however, like Dell’s Inspiron 27 7000.

  • Can users upgrade all-in-one PCs?

    Most modern all-in-one PCs don't allow user upgrades. If user upgrades are supported, they're usually limited to adding RAM or switching out a hard drive. You will need to send the all-in-one back to the manufacturer for any additional upgrades or to have the computer serviced.
