Hello!
I need to open BaseBox case to reach the board, but I want to do it nice. How can I do it without spoiling it exterior and interior?
Remove the two grey stickers that cower two screws, and unscrew them. Then slide out the board.
Thanks, normis! I didn’t notice screw noses under the lid.
Teeny tiny Torx screws? sigh
It’s a T8 size for anyone curious. No, you probably don’t have it laying around, either. Most kits of Torx bits only go down to a T10 if you’re lucky. Latvia must have a shortage of slotted or Philips screws. 
Why do you wish to take board out of case? My tool box goes to t2
Needed to install second radio interface and antenna pigtails.
new print in carton case, new sockets for rp-sma outlets in plastic case, new Philips screws found in newer basebox2.
All good things. thanks MK!
