In this respect, leaving the machines on would be best. However, if the machines are not adequately cooled (by their fans, air conditioning), then heat could build up and cause problems. But this rarely happens because must systems provide for adequate cooling. Note that you should be careful not to block cooling vents on equipment, especially those without fans. As for monitors, leaving them on can cause a decrement in tube life. If you do leave them on for long periods, turn down the brightness so that the cahracters are not visible. Otherwise this constant screen can be "burned in" to the screen's phosphor, which also isn't good. Sound right people? Am I confused?!
