replaced two of these (thermaltake hardcano 14):

with a thermaltake hdd cage which takes up an additional 5.25 bay, but oh well.

it runs nice and cool and quiet but it's silver instead of black and it has no filter and it had to be pushed way back to lock in place and the fucking leds are bright as hell and it only holds 3 drives when they really could have put 4 slots in there but oh well :/ it was only $20 vs the $30+ i paid for each of the individual enclosures and they run a lot cooler now so it works for me. all those cons are minor imo, so i highly recommend this if any of yall are looking for a way to add more hdds and you've got the 5.25" bays free
