Nice set up, you've given me things to consider and some great ideas. My dad has made some wooden end cheeks so I'm good in that department.
Regarding the PS can it be powered at the back? I see the socket on the front panel but is there also a back connection? I'm OCD when it comes to hiding cables.
Do you have a modular grid list of your modules to share? If so that would help me in doing some research on other modules. Thanks for your feedback.
