I only had to add 3 dedicated circuits in the basement for my setup. It does pay to be an amateur electrician, hiring one would have been expensive!
Amen to that. The only way I could run my rigs without running it circuit overloads everywhere was to switch them over to 240v. I'm in an appartment, so my options are limited, but I was able to plugin to the 40AMP 240V outlet for my electric stove, and now all my power problems are over.
