The front of the unit is glass sliding doors which is left open when the unit is on, there is enough room at the back to have banana plugs fitted and still shut the doors its open on 1 side about a 2" gap the other and 3" gap on top there are ventilation slots at the back never had a problem with over heating. I don't think the amps are stressed even when playing loud the front speakers are being run off the emotiva and that's in a separate section but with a solid sliding door my htpc is in there as well but loads of room and the door is open when working, and my powered sub's are in the open dealing with the bass.
