3d Print adapters for Rosewill GPU mining cases

So I was looking at cases… and i cant find the rosewill HDD cases anywhere with cheap shipping… but i can find the GPU cases…

I was wondering if i could pull out the GPU cages, and adapt them into hdd cages, i can 3d print the adapters…

But then id need to make fan mounts… to cool the drives…

What do you guys think, just from the idea of Spinning disk drives, would 3d printing work for HDD cages?
