It's a shame Bitmain hasn't had a good home option (ie low noise) for mining that has decent efficiency since the S3.
You need a spot for miners at this point almost. You can run a Avalon 6 easier in side a room. But S7 would be hard without actually doing some sound mods. Phil has shown a good one in past.
But I would not expect the miners to be any smaller. You either need to be able to get use to it, or have an area. I think it's moving from home miner to hobby miner. That is the trend I see.
Given the crap that Yifu has surrounding him I don't want anything to do with anything named Avalon ever again - even if it costs me a chance at profit.
I have space, but I can't tolerate loud miners where I plan on placing them so I'm out of viable options currently.
And that is a valid thing. I can see why some that lost have hard feelings. I was lucky never loss have had nothing but good from them. Ehash and BlockC both sides I have dealt with.
There is way's to quiet miners out there. Look at Phils rig he showed once he made the S7 quite with something he built behind it.
