Micro desktop for office work

The OptiPlex 3090 Micro packs an Intel Core i5-10500T with six cores and twelve threads into a chassis measuring 7.16 by 7.03 by 1.42 inches. It ships with 16GB of DDR4 memory and a 512GB PCIe NVMe M.2 drive, running Windows 11 Pro out of the box. A wired keyboard and mouse are included so the system is ready for immediate deployment.

Ports and wireless for daily connectivity

Two DisplayPort outputs drive dual monitors while a single RJ-45 jack handles wired networking. Intel Wi-Fi 6 AX201 with 160MHz channels and Bluetooth provide cable-free options when a port is not convenient. Five USB 3.2 ports (one front, four rear) plus a universal audio jack and line-in/out cover typical peripheral needs without requiring a dock.

Step up from older small-form-factor PCs

The 10th-generation i5-10500T moves from four cores to six and adds higher turbo clocks, cutting through multi-tab browsers and spreadsheet loads that stall earlier dual-core or quad-core micro units. Integrated UHD Graphics 630 handles office displays but lacks discrete 3D power, so buyers who want gaming or GPU compute should look elsewhere.
