Hi Gary,

Thank you for taking the time to reply. Your additional comments and 
information are very helpful!

Your factory provided power cable solution seems a good choice. I 
wonder if this is an option for my customer? Grant?  

A quick question for everybody, since Gary has said he is busy: Do 
you think a DIN could be mounted at the rear,bottom of the PCB 
enclosure? If the modules are already 9" deep, even a right angle DIN 
like I mentioned in the last message is more additional depth than I 
would want. I'll have to ask my customer how he feels about soldering 
a cable like yours (Gary's) to the existing DIN, or the PCB power 
points. Perhaps the existing wires from DIN to PCB are long enough to 
allow the existing DIN to be moved to the rear of the bottom, where a 
2" protrusion wouldn't matter? That way it could be returned to its 
original placement if the module were sold. (Though I'd for sure 
prefer the bottom facing power connector!) 

The chest weight for my project is not as critical, since i've been 
told it will mostly be used in Studio work; with only occasional 
travels. But the case will still be light for its appearance, which 
will be aiming to "look" heavy, with an anciently Asian or Nordic 
vibe. Both of which cultures are known for their "moving" chests.<G> 

The power supply for design purposes will needs be inside the main 
chest. But as I've done this kind of work before it will have its own 
area where it is thermally isolated and shielded from the main 
panels, so your valid concerns about heat and shielding have been 
addressed.

Thank you again for your time and the voice of your extensive 
experience. And while I'm replying, Thank You for the music as well!

Kind regards, Randal
