AI-Ready Mini PC Barebone

The MSI Cubi NUC AI 1UMG-025BUS is a compact barebone system built around the Intel Core Ultra 5 125H processor. It targets businesses and developers who want a small-footprint platform for local AI workloads and general productivity. The chassis uses post-consumer recycled plastic and supports VESA mounting for flexible deployment.

Memory and Storage Capacity

Two 262-pin SO-DIMM slots accept DDR5 5200 memory up to 64 GB, giving ample headroom for multitasking and AI inference tasks. A single M.2 PCIe 2280 slot provides the only internal storage expansion. Buyers needing multiple drives or 2.5-inch bays must look elsewhere.

Intel Core Ultra 5 125H Processor

The 14-core CPU combines 4 performance, 8 efficient and 2 low-power cores with an integrated NPU for accelerated AI tasks. Integrated Intel Arc graphics drive up to four displays via two HDMI 2.1 ports and Thunderbolt 4. This specific processor defines the platform’s AI performance ceiling.

Questions about this item

Will the 2.5 Gbps Intel i226V LAN work with my existing gigabit switch?

Yes, the 2.5 Gbps port auto-negotiates down to 1 Gbps so it works with your current switch without any configuration.

How can I verify the Intel Arc graphics are active after I install memory and an M.2 drive?

Open Device Manager in Windows, expand Display adapters, and confirm Intel Arc Graphics appears without a warning icon.

Which parts are included and which must I purchase separately?

The barebone includes the chassis, motherboard and cooling; you must add two DDR5 5200 SO-DIMMs up to 64 GB total and one M.2 2280 PCIe SSD.
