So I bought this mini PC in mind to use the Oculink port with my eGpu dock.
When I plugged it in Windows 11 does not pick it up, you can see it initializes it but does not detect it.
I plugged the same eGPU dock in a K8 Plus Oculink and it picks it up. So if you want to buy it for the Oculink rather buy a K8 Plus.

On the plus side the cooling is much better than the K8 or K8 Plus.
The performance of the GPU is faster than a K8 but slower than a K8 Plus.
GMKTec should maybe upgrade the K8 Plus cooling to the K12 cooling.

I am loving my new PC, the only drawback is that when I am doing intensive work, the CPU starts overheating. ( I have an app installed that lets me know - installed it because my last pc was old and had overheating issues) I have sorted the issue by buying a clear 125mm PC fan and mounting it on standoffs for legs and put the pc on top of it.

But other that that it works exactly as i need it to - I am very happy

What an awesome little PC.
Have set it up in the living room as a Media/Steam/Retro gaming PC and so far, it's performing as expected.
Having space for 2 additional NVME drives is great.
Very happy with this little powerhouse.
