2.5" HDD / SSD Caddy for CD Drive Slot

I'm cycling up an old computer to use as a basic NAS and I wanted to add more drives, but using a small form factor (SFF) computer case, the only option was to add an external bay. In this case, I won't be needing the CD / DVD drive, so instead this will replace that and allow me to put two additional 2.5" hard drives in the enclosure.
