I suggest:

Remove all modules.  Turn on.  If it blows, contact supplier and 
return PS & case.

Add one module, turn it on.

If it blows, report it here with detail.  If not, proceed:

Add one more module...

rinse & repeat.

You need to start with does the case work with no modules and then 
with only one.  After that, add them one at a time.

Bottom line: the only way to test or debug is to limit each test to 
one, and only one, variable in order to isolate the defect.

it is frustrating and time-consuming.

And it always turns out to be the last one you test (joke).

Imagine debugging the same thing when you are designing a "simple" 
circuit from a prototype breadboard before production?  Now add the 
cost of that work into the base price of a module and realize the 
fantastic bargain we get from Dieter for international distribution 
of a wide-range of modules with decent reliability.

done pontificating, hope this helps.

Good luck.
