So I have noticed that my board moves around in the case a little. So I took it apart to find it wasn't screwed down. The holes are there but no screws. So I proceed to screw it down only to find the case wouldn't close properly. So I then used a die grinder to grind down the plastic so the case would seal up tight. Could the board being loose in the case cause vibration problems?
Absolutely that could cause a vibration problem.
