MSI Cubi 5 12M-266US 2024, Core i3-1215U, 8GB, 1TB SSD, Black

The MSI Cubi 5 12M-266US is a compact mini desktop PC that's great for basic office work and multi-monitor setups. It has a 1TB SSD, Thunderbolt 4, and Wi-Fi 6E, but the 8GB RAM and weak CPU hold it back. At $729 to $780 USD, you're paying a premium for the tiny size, not the performance.

The Core i3-1215U is a 6-core chip with a 1.2GHz base clock, and it lands in the 24th percentile for CPUs in our database. That's not great. For everyday tasks like web browsing, email, and document editing, it's fine. You won't feel much lag opening Chrome tabs or running Office apps. But push it with anything heavier, like photo editing or running multiple virtual machines, and the 8GB of RAM becomes a bottleneck fast. That RAM amount sits in the 10th percentile, which is one of the lowest we've seen in this category.

The integrated Intel UHD Graphics puts gaming firmly off the table. Our gaming score for this machine is 8.6 out of 100, which is about as close to zero as you can get without actually being a calculator. You can play Solitaire and maybe some very old indie titles, but anything from the last decade will chug. The 1TB SSD is the one bright spot, landing in the 73rd percentile for storage. That's a lot of fast space for a mini PC, and app load times will feel snappy.

Stacked against the Apple Mac mini M4 Pro, the Cubi 5 looks like it showed up to a race on a bicycle. The Mac mini has a dramatically faster processor, better graphics, and a more efficient design. It's not even close. The Mac mini is the obvious choice if you're not tied to Windows. If you are, the Lenovo Legion Tower 5a Gen 10 and HP OMEN GT16-0364 are gaming desktops that cost more but offer real GPU performance. They're also much larger, so it's not a fair fight on size.

The Dell Tower Plus EBT2250 is probably the closest traditional desktop competitor in terms of office-focused use. It gives you more expandability and better cooling for a similar price, but it takes up real desk space. The Acer Nitro N60-180-UB33 is another budget option that beats the Cubi 5 on CPU and RAM while staying relatively compact. If you don't need the absolute smallest PC possible, any of these alternatives will serve you better in the long run.

At $729 to $780 USD, the Cubi 5 is hard to recommend on specs alone. You can get a traditional desktop with a much faster CPU and double the RAM for the same money. What you're paying for here is the form factor. If you need a PC that disappears into your workspace, that's worth something. But the Apple Mac mini M4 Pro starts around the same price and absolutely destroys this thing in performance. Even a mid-range mini PC from a lesser-known brand will often give you 16GB of RAM and a better processor for less. The value proposition only works if size is your top priority and you never plan to do anything demanding.

The MSI Cubi 5 12M-266US is a mini desktop PC that tries to cram a full workday into a box you could lose behind a monitor. It sits in the $729 to $780 USD range, which puts it in a weird spot. You're paying a premium for the tiny form factor, not raw power. Inside you get an Intel Core i3-1215U, 8GB of DDR4 RAM, and a 1TB NVMe SSD. That's a decent little office machine, but the specs won't turn any heads.

People searching for a small desktop for home office work will find the Cubi 5 checks a lot of boxes. It runs Windows 11 Home, supports Wi-Fi 6E, and has enough ports to drive three displays. The 0.55kg weight means you can mount it to the back of a monitor and forget it exists. But is the MSI Cubi 5 good for anything beyond spreadsheets and video calls? Not really, and we'll get into why.

MSI positions this as a flexible little workhorse for everything from home entertainment to professional tasks. The reality is more modest. It's a competent office PC in a very small package, with a few connectivity tricks up its sleeve. Whether that's worth the price depends on how much you value desk space.

Skip the Cubi 5 if you need any real computing power. Gamers should look at the Lenovo Legion Tower 5a Gen 10 or HP OMEN GT16-0364 instead. If you do video editing, 3D modeling, or run virtual machines, the 8GB of RAM and weak CPU will frustrate you daily. Mac users or anyone open to macOS should just get the Apple Mac mini M4 Pro, which is dramatically faster for similar money. And if you don't care about the tiny form factor, a traditional desktop like the Dell Tower Plus EBT2250 gives you far better specs and upgradeability for the same price. The Cubi 5 is for people who prioritize desk space above everything else.

Should you buy the MSI Cubi 5 12M-266US? Only if you have a very specific need: a Windows PC that takes up almost no space, drives multiple monitors, and handles basic office work. For that narrow use case, it's a solid little machine. The Thunderbolt 4 port and triple display support are genuinely useful, and the 1TB SSD means you won't run out of storage anytime soon.

But for most people, this is a tough sell. The 8GB of RAM is a real limitation in 2025, and the CPU is already showing its age. You're paying a premium for the mini form factor while getting performance that a $400 laptop could match. If you can live with a slightly larger desktop, you'll get far more for your money elsewhere. If you need a tiny Windows box and don't mind upgrading the RAM yourself, the Cubi 5 is workable. Just know what you're signing up for.
