You want to do the rips well, particularly if you are discarding the CDs afterwards .
I've thought about what to do with my CDs. If space was at a premium, I would store the discs in CD binders in disc pages, or some method, and ditch the jewel boxes. I'd keep the liner notes. I could probably store all 600+ CDs in 2 book boxes, but I would have them as backups or to re-rip. For now, they are in a wall rack that holds about 800 CDs.
