Dr. Paul N Morton, MD –
Excellent small form computer. Highly recommend!
I’ve been a fan of this brand for a while now—so much so that I’ve equipped my staff with multiple units over the years. Their previous models consistently delivered solid performance and reliability in our busy office environment. When it came time to upgrade my own setup, I knew I had to try the new Nucbox M3 Plus mini PC.Using the Nucbox M3 Plus has been a real treat. It’s impressively fast, handling everything from everyday tasks to more demanding projects without breaking a sweat. One of the features I appreciate most is its support for a triple monitor setup, which has made multitasking and productivity a breeze. The compact design is both stylish and practical, fitting neatly on my desk while still packing plenty of power.Overall, this mini PC has proven to be a perfect blend of performance and convenience. Whether you’re looking to outfit your team or upgrade your personal workstation, I highly recommend giving it a try.

Very nice mini pc box
Fascinating technology. So small and efficient. Great value. Running a Bloomberg Professional Terminal on it, and it flys. Easily powers 34” LG monitor with great graphics. Thunderbolt or high power USB-C ports would make this perfect. BIOS maintenance/updates are archaic and really different from Dell/HP. Will update review after time.
Audible Reader –
Great for a Plex server
I’m using this as a headless Plex server, and it works great, plenty of power. It does get a bit loud when the fan kicks on, but it’s not that often or for very long. For the price, it performs very well.
Adam Stansbery –
Update: Gets hotter than it should. Great Mini PC for Office use and Retro Gaming plus a Plex Server
This is a really nice little Mini PC with some decent capability and a couple of caveats.If you look at the screenshot of Lexar SSD that comes stock with the PC. The Read/Write Speeds of the 476GB one. You will see that they are standard for Gen3x4 M.2 PCI-e SSD. The second SSD Read/Write speeds is the one that most people may find shocking. As it is a PCI-e Gen3x4 2242 M.2 SSD. Even though the information says it only accepts SATA. It’s a cheap as possible SKHynix I purchased off Amazon for $16. So that’s probably why the write speeds aren’t as good as expected. The empty 2242 M.2 SSD slot is PCI-e and SATA. The motherboard even states it if you see the picture of the inside with both SSD’s removed. The HWINFO64 data shows that it is PCI-e Gen3 compatible as well. So a 2TB 2242 M.2 SSD and a large multi TB 2280 SSD and you could have a decent amount of storage in this PC.I was able to get all three monitor outputs working properly. The only thing I couldn’t get working was HDR for my 4K HDR TV. I have been able to get another PC to output 4K HDR to it so I know it wasn’t that. Probably Windows or Intel driver issues.The one thing that I didn’t like was the fan noise. Any time the CPU had to ramp up for any task. It would be almost as loud as older PC’s loud fans. Looks like the CPU cooler needs to be larger. I did go into the BIOS and set the TDP to 45W instead of the Standard of 35W. That still shouldn’t have that much effect on temps. Even the screenshot from HWINFO64 Sensors shows the slightly higher temps than you may like from it. Possibly a mesh ring around the whole top panel would help with that. Or possibly a bullseye looking design in the top panel.This PC will make a great retro gaming PC and some newer Windows games but I wouldn’t try Cyber Punk on it. The game benchmarks show how well it could possibly handle different games. You could also use the 2242 M.2 SSD as your OS drive and use a PCI-e M.2 External Graphics adapter in the 2280 slot. Making it so you could run many more modern games at much higher settings. But you would still have to deal with the CPU temp issue and possible thermal throttling. Even 2-3 more mm on the thickness of the cooler would help.You could also purchase a low cost DAS and make a great Plex/Emby/JellyFin server out of it.In conclusion.This is a great little PC hampered by a CPU cooler that just isn’t enough to keep this thing as cool as it should.I really do think they should release different tiers for their devices. Say make one motherboard model but only enable things like Thunderbolt/USB 4/5 with the install of the hardware for it for those willing to pay a little higher price. Or even the possibility for an external GPU connection or something like that. Heck a slightly taller PC would even allow a 2.5″ SATA SSD/HDD to be installed. Considering the bottom plate actually has a spot molded in it for one.

Small footprint, powerful and cost effective mini-computer
I love the small footprint of this computer and it is far less expensive than a laptop computer with similar specs. However, I worry about spyware being incorporated into this computer somehow since it is made in China. Even though this computer is a great machine, I really hate buying Chinese products.
Paul G –
Tiny but powerful
Tiny but powerful. I placed the unit on an open rack so ventilation is not a problem. No noise what-so-ever from the unit. Fast response and no connectivity issues. Very satisfied with my purchase and I highly recommend this mini PC.
Kindle Customer –
Excellent unit for basic PC and browsing needs
I was looking for a basic desktop PC and this unit had the best balance of specs and cost. The installation was simple and the NUC has operated just as I expected, very well. The extra USB connection on the front is a plus. In retro spec, a few more ports would have been nice but the gigabit connection makes the unit very fast and makes up for that shotcoming.This was well worth the price.
Amazon Customer –
Not suitable for work
Not very suitable for work purposes. Too slow, frequently freezes and quite noisy

nuxbox2からの買い替えです２は１５か月で壊れました（電源は入るが起動しない、USB端子に電気が来ていないので、電源周りの問題か？）当製品には今のところ問題はありません静かだし、コンパクトでよいですし、価格も納得ですweb閲覧、動画鑑賞、OFFICEソフト使用なので性能的な問題はありません（ゲームしないし）もう一度信じてみます 今度は3年くらいもってくれるといいなあ．．．※２の時のサポートですが、すぐに返事は来ました 静電気によるものかもしれないので、一連の動作（回路の放電後、電源の入れなおし）を試してみてほしいとのことでした結局、回復しなかったので、そう返答しましたが、その後はなしのつぶてです保証期間は過ぎていたので、期待はしてませんでしたが。気に入ってたのですけどね 1年ちょいしか持たないのはきつい

GMKtec M3 Plus Mini PC with Intel Core i9 32GB DDR4 RAM+1TB NVMe SSDThis GMKtec M3 Plus Mini PC will be used as my main computer in my RV for a planned several month tour this summer. Its size and very low noise level make it perfect for my mobile office.I have been using it for 5 days now with no issues. I’m not a gamer so can’t give any advice as to its suitability for gaming.I work mainly with software such as freecad, xojo, and sketchup. I’ve tested the computer with projects I have created on another computer and they all are faster on this mini computer.In the RV I presently have my 50″ TV as the computer screen but will be also using it with a 32″ computer display.I’m attaching some pictures of my setup as well as tests done with Novabench
