When I built my PC, I put a multi-format flash card reader in the external 3.5" bay.
However, I recently upgraded my monitor, and my new monitor has a card reader built in as well.
I'm tired of having 8 "removable disks" on my machine when I really only ever use one, so I'm planning to ditch the card reader I have in my tower.
However, I don't have the original cover for the bay, and I'd like to fill the hole with something useful or cool. I considered using an old floppy drive, but I know I won't ever use it, plus I don't want to clutter up my case with another big ribbon cable.
What are some things I could buy to use up that slot?
