Should. Not sure on your internal cabinet. But on mine I have to tie a string to the powercord end and pull it through so I can fish the cord back through the holes when I put it back in. Future mod...add an out let next to the tv.
Pretty easy to move to the outside. You have to use the speakers in TV. Also make a note of where the cables go into the TV so when you move it back things will still work on the inside. It took me forever to get the connections back where they belonged!
