D-SUB 9in25 Bracket

I needed to add a COM-Port to a PC. All Slots were used and i only got an empty 25-Pin D-Sub opening left for use.
I found this nice monting plate and modified it so it fits perfectly behind the 25-Pin opening.

It is a quite thin plate (1mm) but when the D-Sub Plug is mounted it gains a lot of strenght and when mounted in the case it is even better.
I just used two M3 Screws, nuts and washers to mount it in the 25-D-Sub opening.
