Compact barebone with Intel Core 3 100U

The MSI Cubi 5 1MA-495BUS is a new mini PC barebone built around a 10-core Intel Core 3 100U processor. It arrives without memory or storage so you can choose two DDR4 3200 SO-DIMM modules up to 64 GB total and one M.2 drive plus a 2.5-inch drive. Triple-display output and front Thunderbolt 4 add connectivity for office or light creative work.

Suited to builders who want a small dual-LAN box

This unit fits users who need dual 2.5 Gbps and 1 Gbps LAN ports, Wi-Fi 6E and Bluetooth 5.3 in a compact chassis. It is not for buyers who require discrete graphics, more than two memory slots, or a pre-installed operating system and drives.

10-core Intel Core 3 100U processor

The CPU delivers 10 cores (2 performance plus 8 efficient) and integrated Intel Graphics, defining the performance ceiling for everyday productivity and multi-monitor setups.

Questions about this item

What DDR4 SO-DIMM memory must I buy to populate the two 260-pin slots?

Purchase two DDR4 3200 SO-DIMM modules up to 64 GB total; the board has two 260-pin slots and ships with no memory installed.

Will my existing 1 Gbps network gear limit the dual LAN ports on this unit?

One port runs at 2.5 Gbps via the RTL8125BG-CG controller and the other at 1 Gbps via the RTL8111H, so older 1 Gbps switches will work on either port but only the first port can exceed 1 Gbps.

How can I verify the Thunderbolt 4 port is delivering 40 Gbps after I connect a dock?

Check the Thunderbolt control panel or device manager for a 40 Gbps link width and confirm that connected displays or storage enumerate at Thunderbolt 4 speeds.
