DELL OptiPlex 990 SFF All-in-One 22" i5-2400 3.1GHz 8GB DDR3 512GB SSD Windows 10 Pro

Ready-to-use desktop with 22" display

The Dell OptiPlex 990 SFF All-in-One combines a 22-inch 1920 x 1080 monitor with a compact base that houses a 2nd Gen Intel Core i5-2400 3.10 GHz quad-core processor, 8 GB DDR3 RAM and a 512 GB SSD. Windows 10 Pro 64-bit is pre-installed along with a DVD-RW drive, USB keyboard and USB mouse. It suits office workers, students or home users who want a single-box solution for everyday productivity and media playback.

Verify space, power and peripherals

Measure the desk area for the 22-inch screen and the small-form-factor base before ordering. Confirm the mains voltage matches the unit and that a grounded socket is available. The system provides DVI-D and VGA video inputs on the base plus USB 2.0 upstream and downstream ports, so check that any extra monitors or accessories use compatible connections. No internal expansion slots are described, so plan for external storage or adapters if more connectivity is needed.

Compact all-in-one build with wired input

The black and silver chassis integrates the computer behind the display, reducing cable clutter to a single power cord. A USB keyboard and mouse are included, so no separate purchases are required for basic operation. The DVD-RW drive sits in the base for disc access, while the 2.5-inch SSD keeps boot and application loads quiet. USB 2.0 ports handle everyday peripherals, and the USB Wi-Fi adapter provides wireless networking without internal antenna cables.
