Very impressive! I would love a 'man-cave' like that. One thing you
could look into is improving your connectivity by adding a media server
to your projection room. This way you could play high quality files
without the need to use physical discs. You could even link it to your
house using CAT6 cable to allow full HD to be streamed to the projection
room from a device in your house.
Some media playing software allow for WiFi based remote control from
phones which could prove useful.
