I was running out of space for DVD/CD/BluRay collection, and thought 'what can I do to reclaim some useless space in the process?' I decided to build the cabinet inside the equipment room of my theater......for access to the back of the equipment rack, i just unlatch and swing the cabinet back, it's on hinges, and acts just like a door.
(sorry for the low quality photos, but it get's the idea across)
