Just wanted to say that I've recently received a GK mini and I have used it as the basis for setting up a home server. When I received the unit it was securely wrapped and the retail packaging feels premium.
The goal of my tutorial was to be able to have proxmox running as the base OS, but still have docker (and portainer) running in a lightweight LXC container. I also installed Home-Assistant in a VM.
The GK mini was perfect for this. Even loaded at the moment, it's only running 3% CPU. Memory is around 29% but I expect most of that to be due to the hypervisor.
The unit itself is well made, with a nice finish and despite being extremely light, it doesn't feel cheap. It has a smaller footprint than the 6th gen celeron NUC it's going to be replacing. If anyone is interested in the full tutorial with all commands and screenshots, you can see it here:
In case anyone has been following or is interested to learn more, I've since implemented docker container control with Home-Assistant. You can find more about this here:
