At the worst, I've wasted some time and material and learned something.

Might be better off trying to get some cheap S9s.
I have a mate who has about 5 or 6 bitaxes running in his office & it heats that room pretty well in winter.
I don't think 1 bitaxe is going to give you much heat though.
It's 3 (or 4 if I repair the screw holding the fan) at 6TH/s. Will probably get two additional NerdAxe+ nest year.
