Doepfer

Hi

I have a s6U ystem which is about half doepfer and the rest is 
analogue systems and analogue solutions. at the moment I have it in a 
homebrew wooden case with wooden rails. 

If I moved the whole thing into a doepfer suitcase would I have 
trouble combining the other modules with Doepfer in the same row? It 
seems the hole spacing might be different??

I am wondering how people get around this?
