The OptiPlex 3090 Micro is Dell's tiny business desktop: a 1-liter chassis with a 10th-gen Core i5-10500T, 16 GB of RAM and a 512 GB SSD, so it fits under a monitor or behind a display and runs office work without a fan you notice. It ships with Windows 10 Pro and a Windows 11 Pro license, and integrated UHD Graphics 630 means no gaming or heavy GPU work. Against larger desktops it trades expandability for size; against mini PCs from other brands it stands out for business manageability and easy service access. It suits desk-bound office users, not creators or gamers.
