Why going for this miner which isn't that friendly in all way round?
When you get tired of it, what are you going to do?
In my own opinion, if energy is cheaper or friendly in your location, you can give GPU a trial as it offers more benefits such as no noise, algorithm switching, can be customized and you can also resale when the need arises.
actually if power is cheap you should do some gpu and some asic
if power is cheap (or free) it's better to choice S9
10 x S9 = about $2000 = 140Tx 13 kW/h
2 x S17Pro = about $5000 or more = 125Tx 6 kW/h
and we have ~3000 dollars to pay for cheap electricity

That's about $2,100 USD ( I guess you have to pay some import costs?).
