Compact Business Desktop

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.

Questions about this item

What does the 3.8 GHz turbo speed mean for everyday workloads?

The six-core i5-10500T runs at a 2.3 GHz base and can reach 3.8 GHz on short bursts, giving snappy response in office apps and light multitasking while staying within the Micro's thermal envelope.

Which display outputs are available and what resolutions do they support?

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?

The unit measures 1.42 in wide, 7.03 in deep and 7.16 in high, weighing 2.56 lb, so it fits on a small shelf, a VESA mount or the optional tiny stand.
