Dell OptiPlex 790 USFF all-in-one PC i5-2400 3.10GHz 8GB DDR3 1TB HDD 22" monitor Windows 10 Pro

Compact all-in-one for everyday office tasks

The Dell OptiPlex 790 USFF integrates a 22-inch widescreen LCD into a single desktop unit powered by an Intel quad-core i5-2400 running at 3.10 GHz with 8 GB of DDR3 memory. A 1 TB hard drive and a 16X DVD±RW drive provide local storage and optical media access. Windows 10 Pro 64-bit is pre-installed, and a USB keyboard and mouse are included for immediate deployment in office or home environments.

Low-heat desktop profile with integrated graphics

The Intel HD Graphics 200 subsystem shares system memory and operates within the compact chassis without a discrete graphics card, keeping thermal output modest during typical productivity workloads. Gigabit Ethernet handles wired network traffic while the integrated sound card manages audio, both drawing minimal additional power. Fan noise remains subdued under normal multi-tasking such as document editing, web browsing and video playback.

Space-saving chassis with legacy expansion options

The black and silver all-in-one base uses a 240-pin DIMM form factor and exposes PCI, PCI Express x16, parallel, serial and multiple USB 2.0 ports for peripheral connectivity. This layout supports older specialised cards or adapters that still rely on parallel or serial interfaces, while the integrated monitor stand reduces desk clutter. Buyers needing solid-state boot speed, additional internal drive bays or modern high-speed USB standards will find the platform does not accommodate those upgrades.
