I plan on keeping the original cases in a box until I have the room for them and can afford to get replacement cases that are not cracked or broken.
For the time being though it saves A LOT of room, and looks very nice. Some of the games I didn't have originals for, they were residing in a CD notebook, so this is the first time I can display some of them.

I do prefer all the different logs/artwork on the spine of the originals, but for the time being, this is an effective and great looking solution.
