Like, I appreciate trying to dual purpose energy use... but I dont see a specialized computer that pumps heat as practical. I'm pretty sure it's going to be wasted watts too instead of using a real heater. My 800w box doesn't generate anywhere near as many BTUs as a 600w ceramic box heater. Even though I may joke otherwise. While on hot days in Florida, there is a difference when it's on or off in a room... on the 5 actual cold days we get, it can barely keep my feet warm. When I lived in Colorado... Haha no. The little office I had with a buddy, there were 4 servers in a room, either rendering or doing video analytics crunching. They didnt do shit when ambient was 60f, plus our desktops. Using bitcoin miners as home heaters seems as practical as Juiceroo was to "fresh juice".
