DELL OptiPlex 3090 Micro desktop PC i5-10500T 64GB 512GB SSD + 2TB HDD

Micro form-factor business desktop

The Dell OptiPlex 3090 Micro is a 2021 business desktop in a tiny chassis measuring 1.42 inches wide by 7.03 inches deep by 7.16 inches high. It ships new with Windows 11 Pro and includes a keyboard and mouse. The six-core Intel Core i5-10500T processor runs at a 2.3 GHz base frequency and reaches 3.8 GHz with Turbo Boost, using integrated graphics for display output.

Compact build integration

The micro footprint frees significant desk space and supports VESA or stand mounting options not detailed here. A single universal audio jack and line-in/out handle analogue audio. Two DisplayPort connectors drive external monitors, while four USB 3.2 Gen 1 Type-A ports and an RJ-45 jack provide peripheral and wired network connectivity. An optional port knock-out allows adding serial, PS/2, VGA, DisplayPort 1.4 or HDMI 2.0. No wireless card is installed, so Wi-Fi and Bluetooth require a separate adapter.

Memory and storage headroom

The system arrives with 64 GB of DDR4 memory and a dual-drive layout: a 512 GB SSD paired with a 2 TB hard drive. This capacity handles large datasets, multiple virtual machines and extensive local file archives without immediate upgrades. The tiny form factor limits internal expansion slots and drive bays, so users needing additional internal storage or discrete graphics cards must rely on external solutions.
