thanks for the quick reply.

I am getting to get a server PSU with the PICO adapter so I can have it all run on 1 PSU.

This is the starting process of my building. I will keep expanding and adding 1 new rig when funds allow or when my ROI is gained back from each Rig.

My thought process is that my ROI will continue to decrease with each new rig because I will have the Rig/Rigs before it paid off as well and contributing to the overall small farm investment.
