Hi there
It's just a theoretical question since I don't have the money to do it ;-) However if you would built bigger mining rigs (let's say 30 - 60 cards), is it better to run small systems with 6-8 cards (Asus Prime z270, MSI Z170A, Gigabyte GA-H110 etc) or 13 gpu systems with a ASrock H110 Pro / Asus B250? You're a probably more flexible with smaller rigs regarding cards and psu but need more time to maintain the system. So what would be overall better would you say?
