A 24-inch all-in-one (AIO) chassis with midrange computing hardware is available for $1,239 starting at $1,399 as tested.

Instead of a high-end processor or supercharged workstation-class graphics, the monitor has a three-year warranty and a highly flexible design that allows it to be placed exactly where you need it.

An ergonomically designed workstation is essential for long workdays. In place of mobile CPUs found on all-in-one PCs, where ventilation and thermal issues are paramount, the Dell OptiPlex 5490 uses a more powerful desktop CPU.

The OptiPlex 5490 is a good choice if you must have an AIO, even though many organizations would be better off with a small-form-factor PC and a separate monitor.

With the OptiPlex 5490 series, you can upgrade to an Intel Core i5 CPU from the 10th and 11th generations if you want an eight-core processor.

A limited number of RAM (8GB or 16GB) and storage drive (128GB or 256GB) options are also available. There is only one graphics option—integrated Intel graphics.

The dimensions of the display are 21.3 by 13.5 inches, and those of the rectangular base is 9.9 by 10.1 inches. You can store the keyboard underneath the display when not in use since the neck of the stand is located toward the rear of the base.

Although Dell offers wired and wireless accessories for an additional fee, our test machine does not include a keyboard or mouse.

Rather than the mobile CPUs found on all-in-one PCs, where ventilation and thermal concerns are of utmost importance, the OptiPlex 5490 uses a powerful desktop CPU.

OptiPlex 5490 is a good choice for organizations requiring an AIO, although a small-form-factor PC and a separate monitor are better options.

The all-in-one corporate desktop is a unique system. Business owners in need of entry-level PCs often choose the Dell OptiPlex 3090 Small Form Factor since keeping the PC and display separate permits you to maintain your display investment when the time comes to upgrade.

The all-in-one design does make IT departments more efficient, but you must be extremely space constrained or have very particular requirements to use one.

When you need such a configuration, Dell is your only option. With a desktop CPU inside of a stylish yet traditional design, the OptiPlex 5490 All-in-One offers a sizable warranty.

Even so, we will continue to recommend small-form-factor workstations with separate monitors to the majority of business buyers.
