I have always had a soft spot for mini desktop computers. There is something oddly satisfying about seeing a surprising amount of power come from a box that barely takes up any desk space. That is exactly why the MSI Cubi NUC AI+ 3MG caught my attention. It is a 0.51-liter desktop PC, which is ridiculously small, yet it still manages to pack in modern Intel hardware, plenty of ports, and support for multiple displays.
Of course, this being 2026, the conversation around new PCs almost always circles back to AI. MSI is positioning the Cubi NUC AI+ 3MG as a Copilot+ PC designed for AI-driven workloads thanks to Intel Core Ultra Series 3 processors. Buyers can configure the system with chips up to the Core Ultra 9 processor 386H, while more affordable options use Core Ultra 7 and Core Ultra 5 variants. AI might be the headline feature, but for many folks the real appeal will likely be the hardware itself.
And that hardware actually looks pretty compelling.
Despite the tiny footprint, the Cubi NUC AI+ 3MG supports up to four displays. That is possible thanks to a mix of dual Thunderbolt 4 ports and dual HDMI outputs. For anyone running multiple dashboards, spreadsheets, trading screens, or signage displays, that kind of flexibility could be very handy.
Networking is another strong point. MSI equipped the system with dual 2.5G Ethernet ports, which immediately makes it more attractive for offices, edge deployments, and other environments where reliable wired networking matters. On the wireless side, the machine supports Wi-Fi 7 along with Bluetooth 5.4.
The port selection is surprisingly generous for such a tiny computer. On the front you will find a 10Gbps USB Type-C port, a 10Gbps USB Type-A port, a USB 2.0 port, and a power button that doubles as a fingerprint reader. Around the back there are two Thunderbolt 4 ports, the two 2.5G Ethernet ports, two HDMI outputs supporting 4K at 60Hz, and the DC power input. One of the Thunderbolt ports can even accept up to 98W of power delivery input, which could simplify certain setups.
MSI also designed the system with easier maintenance in mind. The chassis can be opened without tools, making it easier to access components for upgrades or servicing. There is even a built-in cable organizer intended to prevent cables from getting accidentally unplugged. That might sound minor, but anyone who has wrestled with messy cables behind a monitor or kiosk knows how frustrating that can be.
Inside the small enclosure, the system supports two DDR5 SO-DIMM slots and one M.2 2280 NVMe SSD slot for storage. That gives buyers some flexibility when configuring the machine, particularly if they start with a barebone model and add their own memory and storage later.
Security features include dTPM support and a Kensington lock slot, along with the fingerprint-enabled power button. Those are standard business features, but important ones for IT departments managing fleets of small systems.
MSI also says the Cubi NUC AI+ 3MG incorporates post-consumer recycled plastics and uses FSC-certified packaging. The machine carries an EPEAT Silver certification as well, reflecting an effort to reduce environmental impact during manufacturing.
The system ships with Windows 11 Home, though MSI recommends Windows 11 Pro for business environments. Naturally, with Copilot+ branding attached, Microsoft’s AI features are part of the equation. That said, looking at the specs, it would not be surprising to see Linux enthusiasts eyeing this hardware once it becomes available.
At the end of the day, the Cubi NUC AI+ 3MG feels like one of those products where the hardware might actually be more interesting than the marketing buzz around it. Personally, I just love mini PCs. It is always fun seeing how much computing power companies can squeeze into such a tiny box.
The MSI Cubi NUC AI+ 3MG is expected to become available starting May 1, 2026. Pricing begins at $569 for barebone configurations and goes up to $1,669 for fully equipped models that include a three-year Advance Replacement Warranty.
