not sure i'd buy one, but the idea of a cheap cool box is pretty neat, sealed and easy to modify with a hole saw etc....May even have one about in the garage.
So far my one S9 in the garage isn't particularly audible in the house or outside. My 2 board s7 is in an office / server room and i open the door during the day for the heat and close at night for sleep, but it can get toasty if i forget and it'll go into beep/overheat shutdown if i forget and leave too long....I'm also starting to see the rates on it really plumet....Not so much the ROI but 4.7Th isn't pulling down much in terms of coins
