MOTM

My cabinets are all completely closed.  I worry more about dust and 
contamination than heat (I also live on a gravel road so there is 
LOTS of dust).  I elevated my power supplies in the cabinets on 1" 
aluminum frames so that there is air flow around all 6 sides of the 
supply.  I also don't load them anywhere near rated capacity. Heat 
rise is negligible although I have never specifically measured it.
