backstory ITX case only had a 3.5 and 5.25 bay. Tried to mount a second 3.5 HDD in the optical bay, but the holes were wacky (non standard). So I made my own drive cage, and got 3 drives in there. There is 1/4 inch space between each drive, and a 80mm fan blowing directly across them from the farside.
