Is the pcb now tight in the case or is there some room for shifting?
The fan plug taking the shock from resting on the bottom of the case is a very valid point in my opinion.
It does make sense that mechanical shock focused on that point will cause problems.
I wonder if there is enough material to just hollow out a deeper spot for the plug to have some head room instead of removing a window from the bottom?
Nice Mods. I think you will be pleased with it.
