Snapshot
The 30-Second Version
A tiny, quiet Windows box that's great for office work and terrible for games. Get it cheap or get something else.
Pros & Cons
Pros
- Tiny footprint, 0.55kg and basically invisible on a desk 69th
- 1TB NVMe SSD is fast and roomy 65th
- Triple monitor support via HDMI, DP, and Thunderbolt 4
- Wi-Fi 6E and Ethernet give you solid connectivity options
Cons
- Integrated Iris Xe graphics are a gaming dead end
- 16GB of DDR4 is already feeling dated
- CPU performance lands in the bottom third of our database
- Reliability scores are mediocre at best
The proof
Performance
The i5-1235U is a low-power chip built for efficiency, not raw speed, and it shows. Our database puts the CPU at the 29th percentile, which means it's fine for office tasks but nothing to brag about. The 1TB NVMe SSD is the real star here, sitting at the 64th percentile and making boot times and app launches feel snappy. RAM is the weak link at the 33rd percentile, 16GB of DDR4 is workable but not future-proof. The port selection is actually decent at the 67th percentile, which surprised us for a box this small.

vs Competition
The obvious alternative is the Apple Mac mini M4 Pro, which absolutely destroys this Cubi in CPU and GPU performance, but it costs more and locks you into macOS. If you need Windows and want actual gaming chops, the Lenovo Legion Tower 5a Gen 10 or HP OMEN GT16-0364 are real desktops with real GPUs, but they're also much bigger and thirstier. The Cubi's only real advantage is size and silence. If you just need a tiny Windows box for email, Office, and Netflix, this works. If you want to play anything newer than Minesweeper, look elsewhere.

Price
Value & Pricing
Pricing is all over the place in the US, from USD 730 to USD 913 across five listings. That's a USD 183 spread for the exact same box, so shop around before you click buy. At the low end it's a reasonable deal for a compact office PC. At the high end you're paying too much for hardware that's already a generation behind. Newegg tends to have the sharper pricing in our data, so start there.

Overview
The MSI Cubi 5 12M is a tiny desktop that nails the basics for home office work and media streaming, but don't expect it to flex any gaming muscle. You're getting a 10-core i5-1235U, 16GB of DDR4, and a 1TB NVMe SSD in a 0.55kg box that can drive three monitors via HDMI, DisplayPort, and Thunderbolt 4. That's a solid little productivity rig if your day is spreadsheets, video calls, and browser tabs. Just know the integrated Iris Xe graphics put gaming firmly in the 'not happening' column.
Common Questions
Q: Can this run three monitors?
Yes, and that's one of its best tricks. You've got HDMI 2.0b, DisplayPort, and Thunderbolt 4, so three displays are totally doable for productivity work.
Q: Is it good for gaming?
No. The Intel Iris Xe integrated graphics are fine for video playback and light photo editing, but anything beyond casual 2D games will struggle. Our gaming score for this config is 10.7 out of 100.
Q: Can I upgrade the RAM or storage later?
The 1TB NVMe SSD is likely swappable, but the 16GB of DDR4 is probably soldered or limited in a chassis this small. Don't buy this expecting to upgrade your way to a better machine.
Who Should Skip This
If you're looking for any kind of gaming performance, this isn't it. Go get a Lenovo Legion Tower 5a Gen 10 or HP OMEN GT16-0364 instead. And if you want a tiny desktop with actual CPU muscle, the Apple Mac mini M4 Pro runs circles around this thing, just be ready to pay for it.
Verdict
The MSI Cubi 5 12M is a fine little office companion if you find it near the USD 730 mark and your needs stop at productivity and streaming. The 1TB SSD and triple display support are genuinely useful. But the weak CPU, dated DDR4, and useless-for-gaming graphics mean it's not a great long-term investment. Buy it for what it is, not what you hope it could be.
