How many of you like to take the tops off your various pieces of equipment--receivers, televisions, DVD players, etc.--just to look around and see what it all looks like in there? I admit that I like to do this. I have a fascination with electronics and like to look at it all. I realize it probably voids the warranty, though, but I've always wondered if they can really tell if you've opened it or not. So, do you like to take a look at the guts of your equipment?
