MSI Cubi 5 B0A8 2025, Core i5-1235U, 8GB, 1TB SSD, Black

The MSI Cubi 5 B0A8 is a compact office PC with a 1TB SSD and Windows 11 Pro, but 8GB of RAM holds it back hard. It scores 43/100 overall, with gaming at a dismal 9.5/100. Worth considering only at the USD 499 entry price, and only for light office work.

The i5-1235U is a 10-core chip that handles everyday office work without breaking a sweat. Boot times are snappy thanks to the 1TB SSD, and the Iris Xe graphics can push a 4K display for productivity stuff. But that 8GB of RAM is the bottleneck. Our database puts it in the 9th percentile for memory, which is basically the bottom of the barrel. Multitasking will hit a wall fast. The CPU sits at the 31st percentile, so it's not winning any races either. For a mini PC at this price, you're getting adequate performance, not impressive performance.

Stacked against the Apple Mac Studio M3 Ultra, this thing is a toy. But that's not a fair fight, the Mac costs several times more. Against the HP OmniDesk M02-0234 or Dell Desktop ECT1250, the Cubi 5 holds its own on storage and connectivity but falls behind on RAM and overall polish. The Lenovo Yoga AIO F0J20012US offers a built-in display if you want an all-in-one. The Cubi's real advantage is size and those dual Ethernet ports, which is great for niche use cases like a home server or firewall box. For general office work, the competition offers more balanced specs.

Pricing is all over the place. We're seeing USD 499 to USD 1,059 across five Best Buy listings, and that spread is wild for what's essentially the same machine with different RAM and storage configs. The 8GB/256GB version at USD 499 is the only one that makes sense, and even then, you're paying for the form factor more than the specs. At the top end, USD 1,059 for 8GB of RAM is a hard pass. If you're set on this model, hunt for the cheapest config and accept the limitations.

The MSI Cubi 5 B0A8 is a tiny desktop that wants to be your office workhorse. It's got a 10-core i5-1235U, 8GB of DDR4, and a 1TB SSD in a box you can hide behind a monitor. That's a decent recipe for email, spreadsheets, and video calls.

But here's the thing. The RAM situation is rough. 8GB in 2024 is like showing up to a potluck with a single napkin. It'll work for light tasks, but open 20 Chrome tabs and you'll feel it. The storage is solid though, and Windows 11 Pro is a nice touch for business users.

Skip this if you need to run anything beyond basic office apps. The 8GB RAM ceiling and weak integrated graphics make it a poor fit for photo editing, video work, coding with heavy IDEs, or any kind of gaming. Also skip it if you want a machine with a track record, there are zero customer reviews and reliability scores are below average. For the same money, a mid-range laptop or a slightly larger desktop will give you far more headroom.

The MSI Cubi 5 B0A8 is for someone who needs a tiny Windows machine for basic office tasks and values desk space over raw power. It's fine for email, web browsing, and light productivity. But if you're a tab hoarder, a creative professional, or anyone who runs more than a few apps at once, the 8GB RAM ceiling will frustrate you daily. Buy it for the form factor, not the performance.
