Dell OptiPlex 990 All-in-One PC

This Dell OptiPlex 990 is an all-in-one desktop that integrates a 22-inch 1920 x 1080 display with the computer chassis. It runs on a 2nd Gen Intel Core i5-2400 processor with four cores at 3.10 GHz and 3.60 GHz turbo. The system includes 8 GB of DDR3 memory, a 512 GB solid-state drive, and a DVD-RW drive. Windows 10 Pro 64-bit comes pre-installed.

Suits compact office setups.

The integrated design suits buyers who want a tidy workstation with fewer cables and a included USB keyboard and mouse. The small form factor and all-in-one layout limit internal expansion, so users needing a dedicated graphics card or additional drive bays should consider a tower system. Wireless connectivity is provided via a USB Wi-Fi adapter rather than a built-in card.

Fits on a desk with DVI-D and VGA video inputs

The all-in-one base provides DVI-D and VGA video inputs for external display use alongside the built-in panel. USB 2.0 downstream and upstream ports handle peripherals, while the 2.5-inch SSD frees the traditional hard-drive slot. An Ethernet port handles wired networking, and the included DVD-RW drive handles optical media without an external unit.
