Honestly, this build has some very serious problems. You only have one mixer, a linear one. There are no VCAs here for either audio or CV/mod level control. Having the M32 in the cab with everything else is expensive and a waste of space...unless you like paying to power and case a device twice, don't do this. There's nothing to correct the crosspatching issues between Eurorack and the Moog. And why in god's name is the P/S in the _middle_of the row where you'll have the power cable subject to easy disconnection while patching?
OK...you have the M32 already. Do you feel that you've exhausted the possibilities it offers, and this is why you "need" Eurorack, or is this just "something cool" that looks right...until you run smack-dab into the wall of technical issues and MONEY that Eurorack poses?
I strongly suggest some considerable time be spent with VCV Rack before going further. The extreme "Sexy Module" problem above indicates to me that, while you have an idea of what's needed, you don't understand what else has to be there to make those "classics" work in the way they can. There are a LOT of "boring" modules that modular synths require in addition to the snazzy ones; get a copy of VCV Rack and you'll see what I mean.
