GMKtec K8 plus vs K12 vs K16?
Its all about processors in 3 different builds. The K16 7735HS is a rebadged Rembrandt 6800HS from 2022. The K12 H 255 is a lower quality 260/8845HS for the Chinese market while the K8 Plus 8845HS is fully authentic and supported by AMD. When I was searching for my mini last year I wanted more perfo

Best Gaming Mini-PC for $500-$600?
I think the GMKtec K12 is probs good value at $500 (Ryzen 7 8745HS CPU, Radeon 780M iGPU - 32gb RAM, 500GB SSD) vs competitors who have soldered ram and less expandability. The K12 has three SSD slots and you can replace the RAM. Plus it has an OCulink port so you can plug a dedicated GPU to max gam

Any experiences on Linux compatibility for GMKtec NucBox K12 AMD Ryzen™ 7 H 255 Mini PC ?
I got my K12 and am using it for over 2 weeks now, I must say its quite good and no issues whatsoever, I installed Linux Ubuntu latest version on it directly and everything running smoothly without any issues, I got mine barebone, got my own RAM 48GB and 4TB. The CPU Ryzen 7 H 255 works great and qu

Gmktec k8 plus or k12
The third M.2 slot on the K12 is awkwardly placed, there's a capacitor right underneath it so you don't really have space to put a heat sink on your NVME in that slot if that's a thing you're wanting to do. K12 is also down to a single USB4 port vs the two on the K8+ for whatever reason. I went with

I didn't like the original case, so I created and 3D-printed a new one (GMKtec K12).
Couldn't stand the fan noises from either K12 fan, but I do have wolf type ears and the K12 is 10-12 inches away from me on my desk. While u/grykom has done magic for the K12 and solved, I think pretty much all the flaws GMKTEC love to put into their mini pcs last several years, I don't have access

Good mini pc (sold on amazon) that allows for a modern dedicated graphics card to be installed?
I'm running a gmktec k12, it has a dedicated oculink port for external gpu setup. I tested with my old gtx1060 and it works fine, no troublesome setup. Buy egpu dock + psu, 650w is generally fine unless you're using 3090, 4080, 4090, etc. since 650w psu won't have enough power cables. Install nvidia

Where did the SER8s go?
I would suggest looking at better alternatives, like the GMKtec Nucbox k8 Plus or K12. The K12 is slightly better imho since it has 3 SSD slots instead of 2. They're pretty much similar in specs and price as the Ser8 except they have Oculink too. I have the K8 Plus myself, and it's been excellent. O

Gmktec k12 vs k8 plus
I have both k12 and k8 plus. My general use cases: run bunch of vms for managing homelab kubernetes, file server etc. on top of proxmox For the cooling I'm impressed with K12 as in idle state it stays around 36 degrees (celsius), while k8 plus. I replaced k8's thermal paste with a thermal pad, which
