I would reccomend cutting out air vents in the back of the cabinate and even installing small fans there.. I have seen many untimly death of computers due to conjested cabinets. |Drew| I belive it is better to cut/drill out ventilation in the celing of the cabinet, and install a fan up there. The fan does not need to shovel around lots of air. (so you can use a quiet fan ). A fan placed there causes good airflow within the cabinet and it also sucks out the hot air traveling upwards
