I have a small entertainment center and a vip722. I have maybe an inch on each side for air and that's about it. If it's on for a while the top of it gets pretty hot. My only other option is to sit my 42in tv on top of it but it weights 70 pounds. The edge of the tv base would hang over a bit but airflow would be better. Would that be too heavy to sit on top of the vip 722. I could maybe sit a fan in the entertainment center but I tried that once and either forgot to turn it on or forgot to turn it off.
