So what is the opinion of the group? Leave it on, or
shut it off?
 (and I hope I'm not starting a long flaming thread) 
Not flames, but heat.
I have found that things that are prperly designed regarding cooling work
better when left on.
You will pretty much have to determine what is best for each equipment on
a case by case basis.
