MSI Cubi NUC AI+ 3MG review: Panther Lake in an understated mini PC

Tom’s Hardware reviewed MSI’s Cubi NUC AI+ 3MG, a 0.8-liter mini PC built around Intel’s Core Ultra 9 386H from the Panther Lake family.

The system packs dual Thunderbolt 4 ports, dual 2.5G Ethernet, Wi‑Fi 7, removable memory and storage, plus an external power button accessory.

Reviewers praised the compact build quality and feature set, but the fingerprint reader was unreliable.

Its use of a Panther Lake laptop chip in a mini PC highlights Intel’s platform push into smaller high-end desktops.
