MSI Cubi NUC 3MG 2026, Core Ultra 7, 16GB, 1TB SSD, Black

A tiny office box with killer connectivity and a CPU that punches above its weight class. Just don't ask it to render anything more demanding than a PowerPoint.

The Core Ultra 7 355 with 16GB of DDR5 keeps things snappy for everyday work. Our database puts the CPU right around average for mini PCs, which sounds boring until you realize it's doing that in a 0.50kg box. The integrated Intel Graphics are the weak link, landing in the bottom 10% of all products we track. That's fine for Excel and YouTube, but don't even think about gaming. Storage is solid at 54th percentile, and the 1TB SSD means you won't be juggling files. What surprised me? The port selection. Thunderbolt 4, dual HDMI 2.1, dual 2.5GbE Ethernet, and Wi-Fi 7 in a box this small is genuinely impressive.

Stacked against the Apple Mac Studio M3 Ultra, this thing looks like a toy, but that's not a fair fight. The Mac Studio costs way more and targets creators. Against other mini PCs and compact desktops like the Lenovo Legion Tower 5a or HP OMEN, the Cubi loses on graphics but wins on size and connectivity. If you need dual Ethernet and Thunderbolt in a box smaller than a sandwich, the Cubi is your pick. If you need any GPU muscle at all, look elsewhere.

Pricing is all over the map. US listings range from $1,199 to $1,449, and Canadian listings span CAD 1,751 to CAD 2,029. That's a $250 spread in the US alone, so shop around. Best Buy's price match guarantee helps, but the fact that there's no single MSRP makes this feel like a product still finding its footing. For a business-focused mini PC with this port selection, the lower end of that range is reasonable. The higher end? You're paying for the AI branding.

The MSI Cubi NUC 3MG is a tiny box with a big job: bringing Intel's Core Ultra 7 and AI-ready NPU to desks where space is tighter than a budget airline seat. It's not a gaming rig, and it's not pretending to be. What it is, is a compact workhorse for office tasks, video calls, and light AI workloads. The one thing to know? It's a niche machine that nails the niche, but don't expect it to flex beyond spreadsheets and browser tabs.

If you're looking for a gaming PC or anything with real graphics power, this isn't it. Go get a Lenovo Legion Tower or HP OMEN instead. If you need a machine for video editing or 3D work, the integrated GPU will frustrate you daily. This is for spreadsheets, not shaders.

The MSI Cubi NUC 3MG is a purpose-built machine for compact offices and business deployments. It's not exciting, but it's competent where it counts: connectivity, storage, and everyday performance. Buy it if you need a tiny, well-connected Windows box for work. Skip it if you want to game, edit video, or do anything graphics-heavy.
