Review on 💾 StarTech.com Trayless Hard Drive Hot Swap Bay - Removable SATA/SAS Drive Bay - Aluminum (HSB1SATSASBA) by Dan Germain

I like these. I have 3 on my unraid server. The slices were too hot for my taste. There are holes on the back for installing a 40mm fan. I added a 40 x 20mm glass Noctua and the temperature dropped almost 10 degrees. I ran it from the motherboard but they have a 12v connection if you have a 2 pin fan with the correct connection. Hope that helps.
