I have Kaiser, Chevy, Ford, International, Suzuki, Chrysler, GMC, Navistar...but I'll always be a Binder at heart.

I'll buy whatever miner is available at the right price, but given the opportunity I'll want a Canaan from Blokforge. Nick has looked out for me since I since I first bought from him and has proven that he is in it for the long, so that helps a lot. When Canaan goes crazy I buy Bitmain.

By management I meant cables and wiring. I guess it isn't too big of a deal.
I ran 12 721s in my living room for 5 months and my wife tolerated it. She is NOT happy about ONE S9 and 11 721s.

This is even with the S9 getting the coldest air intake at around 5-10C right in front of an open window. I think I've mined more natural gas in the last month than bitcoin... The Avalon miners sound like little hydraulic pumps and the S9 sounds (to me) like a large shop-vac (the "quieter" industrial ones).
I would think it would be pretty easy to quiet them down with some duct-ways shaped like a switchback and lined with fiberglass. I'm getting ready to build some mining pods each capable of 35-36kW that will be located where they need to be nearly silent. Hopefully my plans work out.
