Compact Business Desktop

The MSI Cubi 5 12M-401US is a new mini PC built for office tasks, video calls and light multitasking. Its Intel Core i3-1215U processor and 8 GB DDR4 memory handle everyday workloads within a VESA-mountable chassis that fits behind a display. Windows 11 Pro 64-bit is pre-installed and ready for domain join.

500 GB NVMe Boot Drive

The single specification that decides fit is the 500 GB M.2 NVMe SSD, which holds the operating system and a moderate set of business files. Users who keep large media libraries or project archives on the local drive will need external storage or a larger internal module.

VESA Mount Install

Installation consists of attaching the included 75x75 or 100x100 mm bracket to a monitor arm or stand and securing the unit with four screws. The 65 W power adapter connects via a barrel jack; the only common issue is forgetting to enable Thunderbolt 4 in BIOS before docking high-speed peripherals.
