When it came to putting CDs or DVDs back in their respective cases I was a total nazi sometimes. But times have changed and I've since moved most of my music onto my computer and music player and my DVDs are all in a large DVD holder. My games I have bypasses for those that still need CDs. Nowadays I only keep my non-disc items in their respective boxes like DS games, and I'm still a nazi about that.

I always keep stuff like games and DVD's in their respective cases. It pisses me off when I want to find a certain game or DVD and it's in the wrong case.

Other stuff, such as burned CD's and backups, are all over my desk at the moment. As long as there in a CD spindle or something, then I don't have a problem when trying to find them.

Failing that, I'll put all the CD's into a box and label it 'Important CD's'. Simple.

I keep EVERYTHING where it goes. I even go so far as to fix my family`s shit here when they`re not around.

Other than fixing my niece`s collection, I wouldn`t call this habit anal or stingy. It`s just the right thing to do.

i keep my dvds and cd in their cases, always, and in order(not alphabetical, boxsets in one place, volumens in other, and digipacks in other).
im specially concerned about NOT even allow a fingerprint on the discs, it annoys me a lot.
