Hello,
just purchased the RB912UAG-5HPnD-OUT, now I would like to add a mini pci-e card inside… but actually I realize it is not clear how to open the case ? Please help.
Hello,
you can mail to support@mikrotik.com and they would explane it to you at doing their best!
Looking carefuly at the movie, we can see the guy has the device dissassemled already in the box. He did some prework (also the RSMAs are unscrewed in the video) 
Normally, the bottom part of the device cannot be pulled out.
Yes, it is canned. But you know how to open it?
There are 2 screws which have small covers on the outside of the case.
Thanks. Difficult to remove them but possible.
Please note that RB912G-5HPND has no space to connect 3rd pigtail for an extension card. AUX2 almost sticks to the motherboard leaving no room for external pigtail.
Well, we have installed a Sierra 8705 with it’s own pigtail, and the solution is to use one of the three marked holes, who can be convert to available, with a simply scissors rotating it till get desired diameter…
Look the pic for final results.
Kind Regards.
Max
