Upper right corner. My case had two slots for installing SSDs on the mainboard support frame between the back of the phone and the top cover, which was a death sentence at high temperatures. The m.2 drive was also clamped there. The body (Metallic Gear Neo) left little to no room for breathing and airflow for the discs so I needed a solution to move them around and this worked great. In my case, I can add two more mounts underneath and get a total of 6 SSDs and one m.2, so these mounts can handle whatever storage needs I can have on this machine. This mount was the smallest I could find and worked GREAT. As you can see, in this case the hard drives are placed right in front of the AIO. All I did was drill holes in the black plastic cover that snaps onto the frame and install the bracket with bolts, washers and nuts. 10/10 problem solving.
