Lenovo M Series AIO ThinkCentre M90a Pro Gen 6 Review

The Lenovo ThinkCentre M90a Pro Gen 6 is a premium 27-inch all-in-one desktop with a great screen and clean design, ideal for clutter-free offices. However, its 8GB of RAM and 256GB SSD are major weaknesses for its $2,000 price tag. It's a good fit if design is your top priority, but power users will find better value elsewhere.

If you're looking for a clean, professional all-in-one desktop for your office or home workspace, the Lenovo ThinkCentre M90a Pro Gen 6 is a solid contender. It's a 27-inch AIO powered by an Intel 225 10-core processor and AMD integrated graphics, all wrapped up in a sleek package that saves a ton of desk space. At around $2,000, it's positioned as a premium business machine, and it comes with Windows 11 and a QHD display that can tilt to help with ergonomics. People searching for a 'business all-in-one desktop' or a 'clean setup work computer' will find this fits the bill, especially if you hate dealing with a tower and a mess of cables.

The Intel 225 10-core CPU lands in a solid, middle-of-the-pack position for general computing. It's more than enough for office work, video calls, and multitasking with dozens of browser tabs. The real surprise is the integrated AMD graphics, which score in the best-in-class range. Don't get too excited, though. That high percentile is for integrated graphics, not dedicated gaming cards. It means it's excellent for driving the sharp 2560x1440 display and handling multiple monitors, but it's still not built for 3D rendering or modern games. For business tasks and media, it's impressively smooth.

At $2,041, the value proposition is tricky. You're paying a premium for the all-in-one form factor, the nice display, and Lenovo's business-grade build quality. If a pristine, minimal desk is your top priority, that cost might be justified. However, for the same money, you could build or buy a traditional desktop tower with a much more powerful CPU, 32GB of RAM, a 1TB SSD, and a dedicated graphics card, then pair it with a similar monitor. This AIO is for people who value design and convenience over raw spec-for-dollar performance.

This isn't really competing with the gaming PCs listed, like the Dell Alienware Aurora or HP Omen. Those are different beasts for different people. A closer competitor is something like the Apple iMac 24-inch, which offers a similar sleek, all-in-one experience. The Lenovo has a bigger screen and more port options, but the base iMac often comes with better-optimized software and a more vibrant display. For Windows users, the HP Envy 34-inch All-in-One is another alternative that offers an even more dramatic, ultra-wide screen for a similar price, though it also tends to skimp on RAM and storage at the base level.

Skip this if you're a developer, content creator, or any kind of power user. The 8GB RAM and small SSD will hold you back immediately. Gamers should obviously look elsewhere. Also, if you're on a tight budget or want the best performance for your money, a traditional desktop tower and monitor combo will blow this away in specs. This AIO is purely for those who prioritize a minimalist, cable-free workspace above all else.

Should you buy this? Only if your checklist is very specific. Buy this if you need a professional, tidy-looking PC for general office work, administration, or as a dedicated terminal in a reception area, and you absolutely refuse to have a desktop tower. The screen is great, it's well-built, and it just works. For everyone else, especially developers or power users, you should skip it. The low RAM and tiny storage are serious handicaps at this price. It's a capable machine trapped in the wrong body for most power users' needs.
