Much quieter than a mini PC by another company
I purchased this mini PC to replace a Bosgame mini PC with a bad fan (incredibly loud). The GMKtec is newer, so it has a newer i5 CPU, double the RAM, and double the storage. The GMKtec did cost more than the Bosgame I purchased 13 months ago, but it was worth it.This PC is plenty quick enough to use remote desktop, Office, run a virtual machine, and everything I need in my home office. If I need to edit or transcode video, I remote into a desktop PC in the basement. I could use this mini PC to transcode video if needed, but I would prefer to use a 16 core AMD CPU in my desktop.There are a few things about this PC that I really like. It has 32GB of RAM, a 1TB NVMe, two HDMI ports and 2.5Gb ethernet. I also love that the audio jack is on the back. My previous mini PC had the jack on the front, and that really irritated me for some reason. I was also very pleased to hear that the fan is reasonably quiet. It’s a small fan, so it can be heard when extra cooling is needed, but even then, it is not bad.I visited the GMKtec website and found the support section a bit lacking. The drivers and a copy of Windows were downloaded from Google Drive. I don’t know if the Windows download is anything different than a basic install and not an image with drivers or anything preconfigured for this PC. I downloaded it anyway.Lastly, there was an issue with another small mini PC seller having a virus on their computers from the factory (or at some point before it got to consumers). I scanned this PC with Microsoft’s antivirus and Eset NOD32. Neither reported anything suspicious. I also liked that the only junk apps on the computer were what Microsoft includes. These were not even that bad. It wasn’t like buying an Acer or Dell that have far too many junk apps.This is a fine little PC with more than enough power to use for office work, school work, or other light tasks.

A word of caution for Ethernet users
I’ve used the GMKtec NUCbox M3 as my main PC for six months and, overall, it’s a great value for daily tasks. However, there is one major flaw that potential buyers should know about: the Intel I226-V Ethernet port. This Ethernet controller has a well-documented, unresolved hardware issue dating back to 2023, causing frequent and unpredictable network disconnects. (As reported on Intel community and other online forums.)In my experience, Windows Event Viewer reports 20–30 Ethernet disconnects per hour. Most are so brief you might not notice, but a few times a day, the connection drops for 10–20 seconds, disrupting work and online activities. I’ve tried all recommended fixes—driver updates, power management tweaks, and limiting speed to 1Gbps—but the issue persists, and it’s widely reported across many brands using this controller.If you rely on WiFi, this won’t affect you, as the problem is specific to the wired Ethernet port. But if you need a stable wired connection for work, gaming, or remote access, be aware that this flaw can range from a minor annoyance to a major disruption.I like this PC for its price and performance, but the Ethernet issue is significant enough that I’d rate it 2 stars for anyone who needs reliable wired networking. For WiFi users, it’s a solid 4-star product. If you need Ethernet, consider using a USB or PCIe network adapter as a workaround—or look for a mini PC with a different Ethernet controller.
