Wow, that's a great nice looking and indeed large setup, the A-100PMB together with the A-100PMS12 standing on top of the PMB! So you have now 6*168 HP = 1 kHP ;-) 1008 HP nicely in one large overview :-)
The MDLR case, are you going to use that for when you are going to meet friends or when you want to move with your modules somewhere else (holiday, laying on the beach or on the hotel's room balcony, in one hand a nice drink and the other hand controlling the modules in your MDLR case)? ;-)
Looks like you got yourself a few nice guitars too! I even don't know how to hold one ;-)
Oh indeed, I agree here with Wishbonebrewery, only 300 HP left, that sounds like a serious problem, so next year you buy another PMB+PMS12 set? ;-)
Enjoy your new studio setup together with these new Doepfer cases, now comes the case-versus-module-planning... where to put which module ;-) Have fun and kind regards, Garfield.
