Yeah, the WAF (Wife Acceptance Factor) is important. I got an ear full from the wife and the kids about the Antminers when I fired just one up.

Had to move them from the workshop, where our hangout spot is, to the garage. Nice thing is, the garage is warm now when you're letting the dogs out in the middle of the night. 
I still have to build a "cabinet" for them now that cuts down on the noise, filters the air, and keeps it cool in the summer....

I figured that part would be either an oscillator or a voltage regulator. At this point I'd give them a nice sendoff and pick up either 2 more of those, or another Apollo.
