I have been thinking about turning some old towers into servers and see how that goes. Biggest obstacle is the ISP allow the connection from a residency and not a business.
I was looking into setting up my own servers for hosting and running them from a dedicated secure room in my house, but the ISP won't let me because i'm not on a business plan and can't get one in a residential area.
I am not aware of the regulations in the USA but here we can set up a registered partnership ( A Business name) at a residential address.
It may be worth checking this out in your location to see if it is the same?
