If you dont need to install 2 drives in bay 1 or are fitting a second drive thats a 850 evo 250gb then i recomment one of the other brackets. This m.2 bracket is for the G751 laptop and holds the m.2 drive with room for a naked (removed from case) ssd under it larger than 250gb. This version is closed top for rigidity. You will need to install the naked drive first then install the m.2 inside of this bracket and install this bracket on top. I would suggest the other versions if you are either not installing multiple drives in bay 1 or the second drive your planning to install is a 250 evo which will fit fine with all of the other brackets.
