– Supports up to 128 GB removable RAM via 2x SODIMM slots, a rare feature for mini PCs
– Older Cubi NUC AI+ 2MG maxes at 32 GB soldered RAM; new model better for memory-intensive tasks
– Faster and more efficient Panther Lake CPU compared to previous Lunar Lake processors
– Lighter and more compact design than the older model
– Available in barebones SKUs for cost-saving component reuse by businesses
Unveiled earlier this year at CES 2026, the Cubi NUC AI+ 3MG introduces significant updates to the older Cubi NUC AI+ 2MG as detailed in our review here
One upgrade in particular might matter more then others especially at a time of rapid AI investment: RAM. Unlike most other mini PCs of similar size, the latest MSI model supports 2x SODIMM slots for up to 128 GB of removable memory. This makes it a very unique option in its class, since many competitors are still sticking with fixed memory configurations that can’t be upgraded later on by the end user.
Supporting 128 GB of RAM isn’t anything special in the world of full-size PC towers
But they are rarely seen on mini PCs where soldered RAM or tighter capacity limitations are commonplace. The older Cubi NUC AI+ 2MG, for example, maxes out at only 32 GB of soldered RAM while the larger Beelink GTI15 Ultra can “only” go up to 96 GB via two 48 GB DDR5 SODIMM modules. The 128 GB maximum for the NUC AI+ 3MG makes it a potentially better candidate for running memory-intensive applications, virtual environments, LLMs, and more. This capacity upgrade could be decisive for users who are working with huge datasets or complex virtual machines daily.
Beyond the impressive memory capacity, the Cubi NUC AI+ 3MG sports a much faster and more efficient Panther Lake CPU than the Lunar Lake processor options in the Cubi NUC AI+ 2MG while also being lighter and more compact. The new MSI model is available in barebones SKUs to make it more affordable for businesses that may already have several SSDs and RAM modules ready to be salvaged and reused. This approach reduces electronic waste while also lowering the total cost of ownership for companies who need to deploy many units across there workforce.
