Installing NVMe SSD in Precision 5820 / FlexBay

Hi all,

I was advised by Dell Support to buy the following product when I asked them for suggestions on a second drive in my Precision 5820.

A week, and $250 later, all I got was this gum-stick-sized SSD, with no case or holder of any sort. How do I install this in my machine's FlexBay slot? There's already one in there (factory installed), but it is encased properly, so it fits like it should.

I have been unsuccessful in getting support from Dell on installing this, so I am turning to the community for help.

Any pointers would be appreciated.

Thank you.

PS - I'm running Ubuntu 16.04, but all I need is guidance on the (physical) installation.
