Package Includes: 2PCS Review: Simple and universal - Worked as expected. Very universal for different drive sizes and types. I would buy again but it was a two pack and I don't need them very often. Far better than having a drive short out because it's not mounted properly. Review: Awesome mounts - I built a NAS for unraid using a Dell 3620 tower. Mount is very sturdy. I used the black screws to mount the HDD. I reused the silver screws shown in the photos that came with the PC empty slot filler and the DVD rom drive and boy I tell you it fit perfectly in the holes, you just have to choose the correct holes by inserting it, also I was able to reuse the purple plastic lock (see photo) because I reused these screws. One other review said they had a hard time with the same model PC but it took me only a few minutes to install. Hope this helps someone looking to use the same model PC. ## Features - You can use it for 1 drive,2.5" SSD or 3.5" HDD.Supports computer cases with an available 5.25 inch drive bay;allow to Mount 1x 3.5 - inch （or 2.5 inch or SSDοΌ‰Drive and 1x 12cm fan. - Above Install hard disk , below install the fan.
