no im just wanted to say that a beamer from the smaller (benq/infocus/optoma/whatever) models also may be better if the case is bigger and heavyer. If the beamer is very compact, it may be more constructed for mobile presentations instead of club usage
also airflow you should maybe look at. if i put 2 of my benq's (mp624) side by side, one beamer pushes hot air to the next one.... should not be a problem at your case, but not an uninteresting aspect!
