  • A nice, small PC
Color: Black
I got the Nucbox M3 to run streaming services and web browsing on my TV and have been very happy with it. Pros: Its boots quickly and does everything you would expect from a Windows 11 PC. Web browsing and TV streaming work as expected. It easily runs Moonlight to stream games from my Desktop to the TV and I've had no WiFi bandwidth or latency issues. It doesn't use a lot of electricity, .016kWh when watching YouTube (according to my Kill a Watt) Its small and the black case blends in with the TV and cabinet. Con: My only critique is that it is silent most of the time however during heavy use such as when running updates and installing software the fan has an aggressive ramp and becomes noticeable. Overall I'd recommend it as a light duty desktop, Home Theater PC, or garage/workshop PC. ... show more

  • 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. ... show more

  • I am happy with the purchase
Despite its small size, the build quality feels robust and durable. Boasting the latest 12th Gen Intel Core i5-12450H, this mini-PC handles everyday tasks with ease, but it also does well with lightweight gaming, multimedia consumption, and some graphic-intensive tasks. It adopts a minimalist and compact design, making it easy to accommodate in congested workspaces. It measures about 4.48x4.17x1.67 inches. The added VESA bracket is a thoughtful inclusion, allowing me to mount the PC on walls or monitors, freeing up even more space. The range of ports, including 2 HDMI 2.0 ports, multiple USB slots, Type-C, and more, makes it versatile and compatible with a plethora of peripherals. The BT 5.2 provides a stable connection with a plethora of devices, from headphones to peripherals. The inclusion of a 512GB SSD provides me a rapid boot-up times and quick file transfers. Wi-Fi 6 is a welcome addition, offering faster and more reliable internet connections. The Ethernet RJ45 LAN port is handy for a hardwired connection for improved stability and speeds. With Windows 11 Pro pre-installed, I am able to get access to the latest features and security updates. It combines a sleek design with impressive specs, making it suitable for a variety of usages. From office tasks to casual content consumption, this device handles tasks efficiently. While it might not replace a high-end workstation or gaming PC, it certainly fills a niche for those seeking a compact, powerful, and reliable computer solution. I am happy with the purchase. ... show more
