Review: Does not support 3.5" drives without centre screw hole. - Wanted this to work, but doesn't support 3.5" drives without an extra centre screw hole for mounting. Given how flexible this mount is, it would have been simple to allow for this, but no.
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.

## Customer Reviews

### ⭐⭐ Does not support 3.5" drives without centre screw hole.
*by M***R on 11 March 2024*

Wanted this to work, but doesn't support 3.5" drives without an extra centre screw hole for mounting. Given how flexible this mount is, it would have been simple to allow for this, but no.

### ⭐⭐⭐⭐⭐ Simple and universal
*by J***N on 8 February 2026*

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.

### ⭐⭐⭐⭐⭐ Awesome mounts
*by S***F on 3 May 2025*

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.
