The case holds the 3.5" HDD's nicely. I store the drives in ESD bags and the bags in the slots and it works well
Exactly what i needed.
These thermal pads are the same as you would get with any NVMe enclosure. They are thermally stackable. I had a gap issue with a NVMe enclosure that I had purchased a while ago. The pad that came with the enclosure wasn't thick enough. The NVMe SSD. would get so hot I needed to open the enclosure to cool it down to complete the transfer. I found these pads on Newegg and for the price I figured I'd give it a try. The gap was so wide I had to stack 2 on top of the existing pad to make contact with the enclosures heat sink. I tried a similar sized transfer. No more issues with the NVMe getting too hot and the transfer went strait through. I'm glad I took a chance. Now I don't need to replace the enclosure. If you do find that you need to stack 2 or more thermal pad, make sure there are no air bubbles trapped between them.
The rack itself is shorter, allowing me to leave the front panel cover for the 5.25 bay on. This was a much preferably alternative to 5.25 to 3.5 conversions that have their own front panel.
