Thanks guys!
The main reason why I am doing this is that the drive cages block a significant amount of air to my GPU, which is running hotter and louder than it has too. The drive cages are also one piece altogether, so I can't remove one or two and keep others. There is hardly any airflow getting near my GPU. Right now I cannot order anything from anywhere for awhile, and where I live have very limited tech stores. I guess I'll experiment and try to figure something out.
