Hi Dick,

It looks like you intend the PCB to go over the lip of the front of the 
base plate and screw to it. Any chance of doing the same on the sides? 
Might you put threaded holes along the sides for that purpose? The PCB 
would be more securely held along those sides and, more important to 
some applications, there would be better thermal conductivity from that 
part of the PCB to the frame of the box. You might also be able to 
eliminate some of the stand-off's which would allow more of the PCB for 

Another thought, which might not be compatible with the first thought... 
I see that the box lid has "ears" that come down over the front 
(connector) plate and a screw through each of them. Any chance of 
reversing that and having the ears on the front plate with a screw 
through the cover from the side? That would help with space for 
connectors on the front plate a little.

Looking good!
