I'd like to take apart a DVD player/screen and have it work without the casing?

I'd like to take apart a DVD player, ideally a flat screen dvd player combo and still be able to use the player - but have the computer elements exposed any suggestions? I am looking for any suggestions as to how to take it apart to which players might be the best, I don't need large screens - am also looking at portable players and currently trying to take apart an insignia
