Some people love all-in-one computers; some hate them. I’ve been in offices where every station has an iMac, in environments where everyone has a desktop with a monitor, in workspaces where everyone has a laptop, and in hot desk offices.
I always prefer to have what I need in my bag or a hot desk scenario, but for that workspace that makes sense, like a front desk, an admin’s desk, or a simple in-room computer, for whatever reason, the best all-in-one computers make a lot of sense.
The goal is to have something that is simply all in one; there is no need for extra docks, monitors, adapters, or bulk. Just one display with a machine built into the casing is always there and ready to go. Simple.

That’s where the ThinkCentre M90a Gen 5 thrives. It’s a simple machine. However, that can also be its downfall if misused.

ThinkCentre M90a Gen 5: Unboxing & first impressions
The Lenovo computers are always well packaged, ensuring no damage in transit or delivery. This model specifically had some odd instructions for assembly, though we were able to put the few pieces together to get this machine booted up and running as it should.

At first glance, this machine stood out as more modern-looking, with a professional leaning toward it. It’s designed for an office space as a front desk unit or at a desk in a cubicle. The display, the center of an AIO unit, offers good color accuracy and brightness, though nothing ground-breaking with its FHD resolution.
The ThinkCentre M90a also comes with a bundled mouse and keyboard, though I’d suggest not using it, grabbing a decent Bluetooth mouse and keyboard, and freeing up those ports.
In my initial feel test, setup, and first impression of this machine, it seems capable of what it’s designed for. With ports to spare, this machine could be a true all-in-one, not needing extra docks or hubs to get the basics done as many computers need.

The Lenovo ThinkCentre M90a Gen 5 has the build quality you’d expect if you have any experience with Lenovo products. It’s built well, feels like it will last, and is relatively compact.
That compact design saves overall desk space because you don’t need a monitor, a desktop, or a dock; all you have on the desk is the base to the AIO if even that. If you want to, you can VESA mount this machine and get it off the desk entirely.
If you choose to use the stand, it has adjustable tilt and height with some integrated cable management as well, helping to keep that tidy workspace even more.

ThinkCentre M90a Gen 5: In use
This machine is designed for basic admin and basic office work. In that sense, it handled those tasks efficiently and easily. I started trying to push it under the heavy load of my day, but I felt a bit slow. However, for the vast majority of users who could benefit from a Lenovo AIO machine, you’ll be just fine with the ThinkCentre M90a Gen 5 capabilities.
I’ve been on a single monitor kick recently. I went through my phase of wanting as many monitors as possible, and many of my reviews around here will showcase some images from those days. However, recently, I have become a big fan of simplicity. I realized while using this machine that it doesn’t get much simpler. It’s just a machine that you can leave wherever you are. You have one power cable running into it, and you know it will always be there, ready to work when you are.
If you want to expand your screen real estate, there is an HDMI and a DisplayPort out, allowing you to plug into an external monitor and have even more room to work with. This would be great for a TV if you need to prep and present things in a conference room but don’t want to mount a headless mini desktop behind the TV or if you have a desk running a menu board or display screen. Or, of course, it’s also great if you just want to see what you are working on even better than before.
All around, this machine is solid for what it is; it’s a simple productivity machine for business tasks that don’t require a heavy computational load. For that, this computer is good, but this one feels a tad lacking in the world of high-performing, high-powered machines.
