I am thinking about buying a PS3 but it will be in an enclosed cabinet that has a few ventilation hole at the back. I currently have a 360 in there and leave it open to let the air circulate as I worry it will break. My question is are ps3's reliable? If I am watching a film I don't want the cabinet open, the unit is can be seen in this pic and the ps3 would be getting the bottom right hand shelf. Also, are they noisy in comparison to the PS3?
