I was trying to search for our old posts about this. I had a detailed one.
HuCard, Sleeve, Special Jewel Case (different designs: old gray ones with sticker on back, newer ones with hooks for HuCard sleeve, etc.), Foam, Instruction Manual, Registration Card (sometimes), Pamphlets/Inserts (sometimes, such as Konami)
I'll let others describe standard CD stuff (and the wacky stuff: double-CD cases for manuals/maps, or the "only-slightly thicker" jewel cases with front covers that can handle thick manuals, etc. etc.)
P.S. I purposely made this post confusing!
It really isn't hard.
