You should just go with Giga Watt for hosting unless your power costs are below 3.3c kwh or it's a hobby. I mine at home but it's more for heat in the winter, and use GPU since they are quit. The rest I just have hosted. IF you're in it for profit partner with pros with lowest operational costs. Since you're building a room for mining you won't get the benefit of heating your house, so unless you have cheap electric I don't really see how you're going to be competitive with the giant farms out there.

https://www.coindesk.com/?s=dave+carlsonIf you invest in solar panels and get some tax credits for it then that could make it competitive competing with mega bitcoin farms with cheap electric. Not an accountant but maybe also get a write off using that room in your house for business purposes. Whatever you choose good luck.
