Compact Business Desktop

The DELL OptiPlex 3090 Micro is a tiny form-factor desktop built for office environments. It ships new with Windows 11 Pro and includes a keyboard and mouse. The compact chassis measures 36 mm wide by 178.56 mm deep by 182 mm high and weighs 1.16 kg. It suits deployments where desk space is at a premium.

6-Core Intel i5-10500T Processor

The system runs on a 10th Generation Intel Core i5-10500T with six cores. Base frequency is 2.3 GHz and maximum turbo reaches 3.8 GHz. Integrated graphics handle display output through two DisplayPort connectors and optional video ports. This CPU determines the overall compute ceiling for business applications and multitasking workloads.

64GB DDR4 Memory and Dual Storage

Sixty-four gigabytes of DDR4 memory provides ample headroom for heavy multitasking and large datasets. A 512 GB SSD holds the operating system and active projects for fast boot and load times. A 1 TB hard drive adds bulk capacity for archives and backups. The platform has no wireless card installed; wired networking uses the RJ-45 port.

Two native DisplayPorts are fitted, and an optional port can be configured as HDMI 2.0, DisplayPort 1.4, VGA or Serial, allowing up to three monitors depending on the chosen module.

How much space does the 36 mm wide chassis need on a desk or behind a monitor?
