Barebone Mini PC with Core i7-1255U

The MSI Cubi 5 12M-016BUS is a 0.7 litre barebone mini PC built around an Intel Core i7-1255U processor. It arrives without memory, storage or an operating system so integrators can choose their own DDR4 SO-DIMMs and a 2.5 inch drive. Dual LAN, WiFi 6E and Bluetooth 5.2 are already on board.

Suits DIY builders who want a tiny wired

Ideal for assemblers needing a compact desktop that can drive three displays via HDMI 2.0b, DisplayPort 1.4 and front ThunderBOLT Type-C. Buyers who require a pre-installed OS, larger internal drive bays or memory types other than DDR4 2666 should look at other form factors.

Two SO-DIMM slots supporting up to 64 GB DDR4 2666

The memory subsystem is the decisive spec: two 260-pin slots accept DDR4 2666 modules to a maximum of 64 GB. If your workload needs more capacity or a different memory generation this barebone will not fit the requirement.

Questions about this item

Which memory modules do I need to add to the two 260-pin SO-DIMM slots?

Install DDR4 2666 SO-DIMM modules in both slots; the board supports a total of 64 GB.

Can I keep using my USB 3.2 Gen 2 Type-A peripherals with the front and rear ports?

Yes, the front panel has two USB 3.2 Gen 2 Type-A ports and the rear has two more, all compatible with existing USB 3.2 Gen 2 devices.

How do I verify the Thunderbolt 4 Type-C port is active after setup?

Connect a Thunderbolt 4 device; the OS should enumerate it at full speed and the port will carry DisplayPort 1.4 video alongside data.
