i turned an old computer dvd drive into storage. its a good use of an old drive, and it's a great hiding spot.
Step 1: Open. Cut.
take apart the entire drive. you'll only need the outer metal case, the cd tray, the thing the tray slides in, and the faceplate. dremel off the front of the piece the tray slides in, and cut a big rectangle into the cd tray.
Step 2: Put Together
slide the tray into the holder. get an aluminum tray (the same material as a pie tin) and cut it out and form a basket that will fit in the hole in the tray and is not too deep as to not fit in the metal case. hot glue the faceplate of to the tray.
Step 3: Install
re-attatch the outer metal case. install the drive like you normally would into a computer. to open the tray, stick a paprtclip into the hole to force open the drive, angle the paperclip to the side slightly, and pull it open.
