How much would that really save? Is there a study somewhere demonstrating substantial power savings? Whatever the steady state temperature in the room the AC still has to pump out heat at the same rate it is generated. Raising the room temperature could affect heat exchange slightly because of a steeper/shallower T gradient across the walls/floor/ceiling. For instance, increasing RT would let a little more power drain out through the walls instead of the AC, assuming it is cooler outside than inside. Does a PC doing the same work uses more or less power at 70 or 80 degrees? Off the top of my head I wouldn't expect a huge change in either number for a 10 degree RT change. Maybe it makes a big difference if the machine room is very poorly insulated.
