ok answered my own question lol
heres part of the new plan
trunk i will be building my own case out of fibre glass w00t
i will have an xbox in that with NO dvd drive (ewill make life easier)
and in there a pc also with probably a dvd drive.
these will be ran to the front and hooked to my screen
ok so still wondering about a deck. also does this screen have an output so i can simply change from xbox/pc with the screen and not the deck?
