Lenovo ThinkCentre M90a Pro Gen 6 M90a Pro Gen 6 Raven Black with Stormy Gray 2025

The Lenovo ThinkCentre M90a Pro Gen 6 is an AIO workstation with a monster CPU and endless RAM, but the RTX 4050 and $3,449 price make it a corporate-only pick. If you don't need vPro and an all-in-one, skip it and build a desktop.

We expected the CPU to dominate, and it didn't disappoint—it's in the top 7% of all desktops in our database, crushing multi-threaded dev workloads without breaking a sweat. What surprised us was the RTX 4050: it's fine for light GPU tasks and 1440p gaming at medium settings, but at this price we'd have liked an RTX 4060 or better. The 64GB of RAM is absurdly generous, outpacing 97% of systems we've tested, so you'll never worry about browser tab counts again. Storage at 1TB is solid, though a Gen5 SSD would've been a nice touch. All told, it's a productivity beast that only stumbles when you push the GPU hard.

If you don't need an all-in-one, a tower like the HP OMEN 45L or ASUS ROG GM700TZ will crush this in gaming and GPU tasks for less money. Among AIOs, the Dell XPS EBT2250 offers similar CPU power but lacks the vPro management magic. Truthfully, this ThinkCentre is in a class of its own—it's a corporate workstation that happens to have the screen glued on. Apple's iMac is the obvious creative alternative, but that's a different ecosystem entirely.

For $3,449, you could easily build a desktop with double the GPU performance and a faster SSD. But you'd lose the integrated display, vPro, and that clean AIO form factor. It's worth it only for businesses that specifically need these features and have the budget. For solo devs or home office warriors, there are better values out there.

This is the most overpowered office machine we've ever seen. Lenovo stuffed a 24-core Core Ultra 9, 64GB of DDR5, and an RTX 4050 into a 27-inch all-in-one, and the result is a workstation that laughs at spreadsheets and compiles code in seconds. But it's not for everyone. The $3,449 price tag is steep, and the 8.25kg chassis isn't exactly compact—it landed in the bottom half of our compactness rankings. If you need vPro management and serious CPU muscle in a single package, this is it. For most, it's overkill wrapped in a very expensive screen.

If you're looking for a compact, budget-friendly AIO for casual home use, this isn't it. Grab something like an HP Envy AIO or even a Mac Mini with a separate monitor. The M90a Pro is for businesses that need vPro and CPU power, not for weekend Netflix binges.

Buy this if your IT department demands vPro and you want the most powerful AIO on the market. For everyone else, save your cash and grab a desktop with a proper GPU. The M90a Pro Gen 6 is an impressive niche machine, but its price and mid-range graphics keep it from universal appeal.
