Lenovo M Series AIO ThinkCentre M90a Gen 6 Review

The ThinkCentre M90a Gen 6 AIO has a fantastic 20-core CPU and great ports, but its graphics are weak and reliability scores are low. It's best for office workers who hate cables, not for gamers or creatives. At $1309, it's a questionable value.

The Lenovo ThinkCentre M90a Gen 6 is an all-in-one desktop that tries to do a lot. It's built for business, packing a surprisingly powerful 20-core Intel CPU and a clean, cable-free design into its 24-inch frame. But it's not trying to be your gaming rig or your creative powerhouse. This is a machine for keeping your desk tidy and your spreadsheets humming.

That 20-core Intel CPU is the star here. It's a standout performer, ranking in the 86th percentile, and it'll handle heavy multitasking and complex calculations without sweat. The ports are also top-tier, with Thunderbolt and HDMI 2.1 out for connecting high-res monitors. The weak spots are clear: the integrated Intel graphics are mediocre, ranking in the 38th percentile, so gaming or video editing is a no-go. The SSD and RAM are just solid, middle-of-the-pack specs. And our data shows its reliability score is disappointing, falling behind most other desktops.

At around $1309, this is a tough sell. You're paying a premium for the all-in-one form factor and that strong CPU, but you're getting mediocre graphics, average storage, and questionable reliability. If you absolutely need a tidy desk and CPU power, it might be worth considering. But for most people, a traditional desktop tower will give you better specs and more upgrade flexibility for the same money.

Compared to gaming desktops like the HP OMEN 45L or the Alienware Aurora, this ThinkCentre is a different beast. Those machines crush it in graphics and gaming performance, but they're bulkier and cost more. Against other business PCs, like Lenovo's own T Series towers, you lose the sleek AIO look but gain better reliability and often more storage options. The MSI Aegis or Asus ROG NUC are more balanced for mixed use. Basically, this ThinkCentre trades graphical power and reliability for a clean desk and a fast processor.

Skip this if you play games, edit videos, or need a reliable machine for long-term use. The graphics are a letdown, and our reliability data is concerning. Also, if you want to upgrade your RAM or storage later, get a traditional desktop tower instead.

Buy this if you're in a corporate or home office setting where desk space is sacred and your work is purely CPU-intensive, like data analysis or coding. You need that tidy look and the raw processing threads, and you don't care about games or creative apps. It's a niche machine for a niche need.
