for the star rating, I note 4 stars because a location to side fan has no grid pierced. this housing can be broken down 4 sides (behind top and sides) .is for receiving a burner and a memory card reader. with no usb 3 front it is imperative to take it with a player with usb socket 3. has a reset button, which is perfect. the dimensions are. I regret that there is no indication of the mounting. may need to be drilled to fix the walls of the fans.
