Of course! What's even the point of having physical media if you're not going to keep it fully intact?

If my goal were to save space, I'd just rip everything to my computer and get rid of the discs themselves, too.

Yeah, I kept all the cases. There's one big tote in my basement and another couple cardboard boxes. I'm not ready to ditch the covers and liner notes.

I do. I even get steelbooks for the repeat watchers when they are available and I have the coin

I'm not a "collector" but so far my physical media is a mixture of both. I just don't have the storage capacity for cases but I keep cases for things I really like or box sets.

Always keep the cases.

Keep the cases so you can reorganize alphabetically, by genre, chronologically, ... and then step back and look at it.

Absolutely, they get too easily scratched without them. I get rid of the paper covers though, they just feel like ads.

If I would have had the physical space, I would have. Sadly, I didn't have such space, so my discs ended up stored on spindles.

Ages ago to save space, I got rid of all my CD cases, but kept the disks and the booklets and back cover inserts. Still got them all, but I do kind of wish I hadn't dumped the cases.

I gave them to a charity shop though so they would have them as spares, so at least they weren't totally wasted.

Now my vinyl on the other hand... You can take my sleeves from my cold dead hand!

Music, yes; movies no.

For various reasons, I like having the "entire package" of a CD or cassette (though I don't have many of those any more, just a few local bands that no longer exist). Not just the little booklet, but the covers too. I tried using one of the "books" that holds the discs and paper materials, but it never worked right. It's fine for stuff that didn't have any kind of covers or whatever, and CD singles, but I like the experience of opening the case, using the disc and having the materials there all in one package.

Vinyl is totally different thing to begin with.

Movies, I ditched individual cases a long time ago. The only ones I keep are special editions and whatnot.
