I'm in Alaska and just got an s9 for this purpose, although I'm going to be doing the full build myself.
I've got the bare s9 with new phantek T30s warming my feet now. Running at 750 watts and getting almost 10 TH/s (approx 79 W/Ths) it's about the same noise level as my previous heater and using less electricy so it's basically free sats.
I still need to swap out the psu fan, and then it will be even quieter.
And then 3D printing the case, assuming I can get my printer to do it right in less that 10 tries 😅
