To my mind it isn't the snake you are looking at but the 'landscaping' I enjoy mine if the snake is out or not. In a class room I don't think a rack is a good idea. The room is not going to be warm enough for a rack to run properly. There is a reason why 95% of racks are in rooms that are 80ºF it is too hard to hold proper ambient temps and cool end temps in rooms much less.
