I maxed out 100A service in a 525sq.ft. studio.  6x 6-card 1070 rigs, 6x 7-card 470 rigs.  If I wanted to use the stove I needed to switch out the server PSUs.  If I wanted to use the microwave I needed to shutdown a 470 rig.  I wore heavy-duty noise canceling headphones during the day and slept with earplugs in.  I made it through fall, winter and spring in Chicago.  Obviously I never turned on the heat.  Once the outside temperature started getting above 60F in spring it would get to about 80F inside despite the massive fans and airflow I had setup.  I made enough money in 9 months of living like this to buy a house and scale up.

Is it possible?  Yes.  Does it come with sacrifices?  Yes.  You decide if it's worth it.
