Size: 32GB DDR5+1TB 7840HS
I've had a Intel NUC with a Core i5 for a little over 6 years but it was starting to show it's age a bit. One of the ram slots died, it would not boot if I had any ram installed in the second slot. The CPU fan was also wearing out; 3rd party options that I tried were less than stellar. So after dealing with those issues for a little over a year, I decided it was time for a replacement. It was a good pc but it's time had come. Wanted to stay with a small form-factor pc for various reasons. After checking out other options that are available, I settled on this NucBox K6 from GMKtec. It has a Ryzen 7 7840HS cpu, 32 GB of DDR5 ram and 1 TB NVME drive. I added a spare 1TB NVME drive I had to double my storage as well. Small footprint, supports 3 monitors, option to upgrade/replace components as needed with 2 user-serviceable slots for both m.2 drives ram. It's also fairly easy to take it completely apart for cleaning the CPU fan. The auxiliary case fan is a standard 40mm x 10mm pc fan; that will be simple to replace when/if the fan dies. Ticks all the boxes for me. After working with this for over a month, I've had no issues. There was no extra bloatware installed out of the box that I could find. Windows 11 has been running just fine with updates on. I do a little bit of everything with this computer: I've ripped several hundred DVDs and Blurays (with an external Bluray drive and MakeMKV) re-coding said rips with Handbrake for our media server. Some video editing with CapCut. Some light gaming. FreeCAD for designs for my 3d printer. Photoshop. Inkscape. This computer runs circles around my old IntelNUC. All that said, one thing I don't like about this computer is that there is only one USB C port on the front. The USB C port is what is used for the 3rd monitor hookup. I did not want a cable sticking out of the front for this, so I took it upon myself to address this issue. I designed a new top to replace the top from the factory. It houses a short USB C extension cable with a panel mount jack for ease of installation in the new upper housing. Works great. I can have everything plugged in to the back with minimal excess on the front. The extension plug is also loose enough in the new extended lid to unplug and move aside if I need to plug something in to the USB C port without having to take the new housing apart. I didn't print it with the best settings and it wound up being a little bit taller than I'd like but works for my needs now. I saw another review complaining that the AMD Ryzen 7 PRO 6850H is not running at the speed listed. The listing on Amazon states 4.7ghz, and his is showing it running at 3.2ghz. The speed listed on the Amazon listing is the turbo speed. If you check AMDs website on the CPU you'll see it's normal speed listed at 3.2ghz and it turbos up to 4.2ghz. This CPU is running at spec per AMDs webpage. That is not the CPU that came with mine but I wanted to share that info to avoid confusion. The CPU in mine runs to AMDs specs with no issue. Very happy with my purchase, I hope to get many years of use out of this.

Size: 32GB DDR5+512GB NEW H 255
As a PC enthusiast since the dial-up era, I’ve built my share of rigs to fuel epic Command & Conquer: Generals and Zero Hour sessions. I’m not chasing high-end FPS titles—give me base-building and Shockwave tank rushes at 60fps any day. The GMKtec K12 Gaming Mini PC, with its AMD Ryzen 7 8745HS, 32GB DDR5, 512GB SSD, and Radeon 780M graphics, has become my go-to for strategy gaming and everyday tasks. Here’s why this tiny titan earns my nod. This thing is small—think hardcover book size—yet it’s a beast. Setup was a breeze; Windows 11 installed without a hitch, dodging Microsoft’s TPM 2.0 roadblocks. I went local user mode for privacy, and it just worked—no workarounds needed. The K12’s quiet operation is a standout; even during intense Zero Hour GLA campaigns, the fans barely hum. It’s a far cry from the roaring towers of my past, perfect for late-night gaming without disturbing the house. Performance? Stellar. The Ryzen 7 and 32GB DDR5 chew through Generals and Zero Hour at 1080p, delivering silky-smooth battles and fast load times thanks to the NVMe SSD. The Radeon 780M handles particle-heavy Scud Storm effects flawlessly. I’ve also dabbled in Age of Empires II Definitive Edition—high settings, no lag. Multitasking is effortless, with browser tabs and Discord running alongside game sessions. Three M.2 slots and dual 2.5G NICs scream future-proofing, though I’d grab a USB hub for extra peripherals. Downsides? The port selection (HDMI 2.1, USB4, etc.) is solid, but heavy peripheral users might need a dock. Thermals are great, but place it in a well-ventilated spot for marathon sessions. At roughly $500, it’s a steal for the power. For C&C fans like me who want a compact, quiet rig that crushes strategy games without the hassle, the K12 is a winner. Five Stars—ready to command and conquer.
