Cool name, cool idea. Industrial Flower Factory make low power draw, small footprint, low noise computers. I reckon that my hulking old AthlonXP is one of the major power draws in the house, and it certainly creates the most noise pollution.
IFF’s machines are a little pricey, but when they’ll save so much of your hydro bill, that’s got to be good. They’ll also preinstall Linux, which make me happy.
