I quite like VINT boards as they have small form factor and a nice plastic box. The plastic boxes can be fixed using 2.5mm screw to a mounting surface.
I think the boxes should have opening for a 3mm screw instead of 2.5mm. The reason for this is that 2.5mm falls into 'precision' category so it's not normally stocked by enthusiasts, requires tools that are less common etc. Second, the PCB boards (inside the box) have opening for 3mm screws so the only change would be making a slightly larger mounting holes on the plastic boxes.
For example, I end up drilling through plastic boxes and then using 3mm screws to mount boxes into standoffs and then onto the mounting surface.
Just a suggestion for your consideration, seems like an easy change to achieve a more standard format.
