Even as cheap as the B. 2 x 140 hp is, you're still paying extra to house and power the M32 in this setup. Not cost-efficient. Leave the Eurorack cab for the things that NEED it, and keep the Mother-32 where it normally belongs.
Also, take Jim's advice here and try and find a better power solution. Just remember that you'll want power that exceeds the draw of the collected modules by about 1/4th-1/3rd of the total to avoid inrush issues at power up and to keep the P/S running cooler. It's the biggest source of heat in ANY modular build, and since heat can also equal instability for various circuits, cooler is what you want.
Being unfamiliar with modular synthesis and building a rig at the same time is generally not going to work out well. Instead of going further with this, I strongly suggest downloading a copy of VCV Rack. This is billed as a "Virtual Eurorack", which isn't wholly accurate inasmuch as some VCV modules really are quite computer-dependent. But the operating, programming, and build principles are 100% the same as Eurorack as long as you don't overtax your computer's resources. By working with this for a while, THEN coming back to a build attempt, you'll find that making sense of the plethora of modules on MG becomes WAY easier.
