I have an Antec ATX case and am looking for another of those plastic clip in fan adapters for the second HDD bay. Does anyone know where I can get one, or even their proper name so that I can run a search?
You're probably going to have to contact Antec at email@example.com. I did that when I needed a replacement 120mm fan holder, which they discontinued, unfortunately. As for the 80mm holders, I doubt they would be out of those.
