Barebone mini PC with Core 5 120U

The MSI Cubi 5 1MA-494BUS is a compact barebone mini PC built around an Intel Core 5 120U processor with ten cores. It ships without memory or storage, letting integrators choose up to 64 GB of DDR4 3200 across two SO-DIMM slots and add a 2.5-inch drive plus an M.2 device.

Upgrade from older small-form PCs

Replacing a legacy desktop or first-generation mini PC with this unit adds Thunderbolt 4 at 40 Gb/s, dual LAN at 2.5 Gbps and 1 Gbps, and Wi-Fi 6E with Bluetooth 5.3. The jump is worthwhile when a workflow needs faster wired throughput, modern wireless bands, or a single-cable dock for multiple displays.

Fits into space-constrained builds

The chassis accepts two DDR4 SO-DIMMs, one M.2 module, and one 2.5-inch bay, while the front Thunderbolt 4 port and two USB 3.2 Gen 2 Type-A ports handle peripherals and video. Triple-display support frees desk space by reducing the need for a separate docking station.

Questions about this item

What size SO-DIMM slots does the Cubi 5 1MA-494BUS have for memory?

It has two 260-pin SO-DIMM slots that accept DDR4 3200 modules up to 64 GB total.

How do I install memory and storage in this barebone, and what step is often missed?

Remove the bottom cover, insert DDR4 SO-DIMMs into both slots for dual-channel operation, install a 2.5-inch drive in the internal bay and an M.2 drive in the single slot, then secure each with its screw before reassembling.

Which replaceable parts will need attention after extended use?

The SO-DIMM memory modules, the 2.5-inch drive, the M.2 drive and the internal Wi-Fi 6E / Bluetooth 5.3 module are all user-replaceable components.
