Can you post a picture of where you'll be placing it ? That would be super useful. The spot I chose for my Outlaw is on a lone bottom shelf. The back of the unit has a backing, but I sloppily cut a big portion of it out where my interconnects as well as binding posts are arranged so it fits better. It also serves to cross ventilate the unit, which is un-doubtfully a very good thing.
I have yet to feel my Outlaw get anything more than mildly warm, and I'm sure that the aluminum chassis plays a big role in that. Still though, more ventilation is always better than less, IMO.
