Thanks for this guide,
I managed to set it up and got it working on an i7-477K.
However, first I installed the wrong app in unraid since ich777 image didn't appear and struggled a while until i realised it.
Could be worth a note in your main post that when searching for Intel-GPU-TOP in unraid Apps it doesnt show, I clicked show results from Dockerhub and found the wrong image.
I had to search ich777 Intel-GPU-TOP to get it to display!
Cheers
