Emax

I would leave room for venting but usually processors can handle so much heat. I had a 
Powerbook a few year ago, we open it up and the aluminum covering the processor was 
fried! we removed the heat protection and we were able to see the actual processor in the 
inside. Fried and working. The computer broke down later on because some component 
that wasn't able to recharge the batery but the processor was up and running. That was a 
Powerbook G3 Pismo. 

I believe circuits can handle an enourmous amount of heat but is better to treat them 
nicely. If you ever need to use the rack in a concert I believe you can cover the vents as 
long is not under too much heat from the outside, but in studio operation have it cooling 
just fine.
