I just got my Onkyo 797 and I am very happy with it. I jsut noticed, when I was moving it, that the side panels, do not fit very well, or maybe this is how it is meant to be. At the bottom of the middle of the side panel, I can push it in, and it pops back out, about .5cm, is this somethign to worry about? Also, I saw a fan on the inside of the 797, when does it kick in, is it based on temp or on output? Thanks.
