Two.

One is the 2006 DVD of the original theatrical release of Star Wars. It's on a small shelf of a desk return in my home office along with about 15 other DVDs & Blu-rays, for easy access. It's in a single-DVD case, with a cover I made (the original one-sheet).

The other is a DVD of extras from one of the previous releases. I got it off Ebay so I could rip the audio from the original theatrical trailer of Star Wars and add it to my Star Wars soundtrack CD (which I did). That DVD is in a drawer with all my DVD sets of TV shows. Those take up too much shelf space and have various styles of packaging.
