I'm looking into the same setup for my home lab, only I've got a question about the hybrid architecture from Intel.
I'm currently running on old 4th gen intel core HW in a testlab (and alsowant to get away from broadcom/vmware asap).
Can you use both the E and P cores? And did you do anything special to make it work?
Is the box getting warm under full load, or can you still touch it without getting burned?
I've got some experience with industrial grade boxes, but they tend to burn you fingers when you touch them under full load.
Please let me know
