which other factors should i consider before setting up my mining farm.
As you conider the location, also consider security. Your equipment are expensive and certainly you would not want to put them in an environment where the rate of stealing is high. Ask questions and do your research about your location to know if the area is safe first before you decide on which security measures to employ in securing your mining farm from criminals.
I think the major things to be considered has already be listed by those who gives opinion but I will like to ask if you have considered the energy properly and the hash rate of the environment and see how supportive the area are to the action you plan taking, mostly important not understand rating the security in general to avoid effort in vain. All this is in place congrats as it's a good move.
