MSI adds Intel Core Ultra 3-powered NUC mini PCs to Cubi line-up

Following on from last week's announcement of the low-power Cubi NUC TWG mini PC, MSI has introduced another Cubi NUC system built for more demanding applications, powered by the new Intel Core Ultra 3 CPUs.

The Cubi NUC AI+ 3MG includes dual Thunderbolt 4 ports and support for up to four simultaneous displays. Networking is handled by two 2.5G Ethernet ports, giving the system redundancy and higher‑bandwidth options for enterprise environments.
