My observations after installing a Samsung 850 EVO mSATA drive into the Omnia :
- My Turris Omnia uses some kind of black (plastic ?) washers for some screws (4 of the 5 long screws securing the main board and some of the bolts used with the standoffs/spacers securing the mini PCI Express cards).
- I had to permute 2 WiFi cable because one 2,4 GHz (small WiFi card) was too short. Thanks to Diplexer connection for nice explanations.
The Samsung 850 EVO (250 GB) is recognized without any issue. The two WiFi cards are OK.
