Our take on the Lenovo ThinkCentre M90A Gen 3 All-in-One

The ThinkCentre M90a Gen 3 is a 23.8-inch business all-in-one built around a 12th-gen Intel Core i5 six-core processor with integrated UHD Graphics 770. Its selling point is expandability unusual for an all-in-one: DDR4 memory support up to 128 GB, a single SSD slot, two DisplayPort outputs and a full set of USB-A and LAN ports. It suits office, front-desk and kiosk deployments where a tidy single-unit desk matters more than gaming or creative performance. Against consumer all-in-ones it trades styling and discrete graphics for serviceability, security features and a longer support lifecycle. The 8 GB RAM and 256 GB SSD base configuration is modest, so buyers should plan to add memory and storage.

Questions and answers

Can I upgrade the RAM and SSD myself?
Yes. The M90a Gen 3 is designed for tool-less access, and memory can go up to 128 GB DDR4. There is one SSD slot, so plan storage around a single drive.
Can it drive two external monitors?
Yes. It has two DisplayPort outputs, so you can run the built-in screen plus two external displays, depending on the panel and adapter setup.
Is it good for gaming or video editing?
No. UHD Graphics 770 is integrated graphics meant for office work and light media. Gaming and heavy video editing need a discrete GPU, which this configuration lacks.
Does it come with Windows 11 Pro?
Yes, Windows 11 Pro is the installed operating system, which adds BitLocker, Remote Desktop host and domain join over Home.
How does it compare with the ThinkCentre M90a Pro?
The Pro variant adds a higher-resolution display and stronger configuration options. This Gen 3 model is the more basic business all-in-one, with the same upgrade-friendly design.
Is the webcam good enough for video calls?
It handles everyday meetings, but owners describe it as adequate rather than sharp. A dedicated external webcam is a reasonable upgrade for frequent calls.
Where is the Lenovo ThinkCentre M90A Gen 3 All-in-One cheapest?
At Newegg, for $2,743.91, as of our latest check.
