A:AnswerThere is no tower in the new "all in one" computers. The screen is 21 1/2" and everything is built into the screen (I assume in the back) There are 2 USB ports along the left side of the screen along with a port for headphones and there are 2 USB ports in the back. There is a CD player/burner toward the top of the right side of the screen. The one I bought came with a wired mouse and keyboard which I did not use as I had a wireless Logitech mouse & keyboard that I synced to the computer using one of the USB ports.

A:AnswerJust adding to the previous response, to further clarify this, you can play multiple disks in the system; however, you won't be able to play a Blu-Ray disk or other 'special disks' without installing some sort of "Blu-Ray player" on the system . I was curious as well, so I.... googled it.
