Lenovo ThinkCentre M90a Gen 6 Raven Black 2025

A fast, compact business AIO with killer connectivity that's held back by weak graphics and a fiddly stand. Buy it for the office, not the game room.

The Intel Core Ultra 7 265 chip is the star here, landing in the 89th percentile for CPU performance in our database. That means it chews through office tasks and multitasking faster than most desktops we test. The 16GB of DDR5 RAM is solidly average, so it won't bottleneck your workflow, but the integrated Intel graphics are a weak spot. You can forget about modern gaming or heavy 3D rendering. What surprised us most was the connectivity: Thunderbolt, dual USB-C, HDMI in and out, and Wi-Fi 7. It's one of the best-equipped AIOs on the market for hooking up a second screen or daisy-chaining peripherals.

The M90a isn't trying to compete with gaming towers like the HP Omen 45L or ASUS ROG GM700TZ, and it would get absolutely smoked in any graphics test. Its real competition is other business AIOs and compact desktops. The Apple Mac Studio M4 Max is in a different league for creative work and raw power, but it also costs significantly more and requires a separate monitor. If you're deep in the Apple ecosystem, the Mac Studio is the better tool. For Windows-based office work where desk space is tight, the ThinkCentre is a smarter, more affordable pick than Apple's offering, and its port selection embarrasses most competitors.

Pricing is all over the map, ranging from $1799 to $2389 across vendors, so shop carefully. At the low end, you're getting a solid deal on a fast, well-connected business AIO. At the high end, you're overpaying for specs that don't justify the premium. The sweet spot is finding a configuration near that $1800 mark. For that, it's a fair price for a machine that'll be a reliable office companion for years.

The Lenovo ThinkCentre M90a Gen 6 is a business-first all-in-one that gets the important stuff right. It's fast, compact, and packs a genuinely impressive port selection into a clean 24-inch package. If you need a no-fuss desktop that handles spreadsheets, video calls, and a dozen browser tabs without breaking a sweat, this thing delivers. Just don't expect it to be a gaming rig or a creative workstation, and definitely pay attention to which stand you're ordering.

If you're looking for a machine that can game, edit 4K video, or handle 3D modeling, this isn't it. Go get a desktop with a real GPU instead. And if you need a highly adjustable screen for ergonomic reasons, the limited stand options here will drive you nuts.

The ThinkCentre M90a Gen 6 is a purpose-built office machine that excels at its job. It's fast, well-connected, and takes up minimal space. The integrated graphics mean it's a non-starter for gamers or video editors, and the stand situation is genuinely annoying. But if you need a reliable Windows AIO for business and you can snag it at the lower end of its price range, it's an easy recommendation. Just budget for a decent wireless mouse and keyboard, because the included wired ones feel cheap for a machine of this caliber.
