OK...for starters, this isn't what I would call a "learning" build. In fact, NOTHING that fits into these little "beauty cases" would be able to manage that unless you go with modules under 4 hp...at which point you run into the ergonomic issues of lots of tiny knobs with no space for fingers. You see these WAY too often on YouTube...and I (and an experienced bunch of others here) consider the vast majority of the ones you see there to be essentially useless as all-around modular synths.
In short, this is heading in the wrong direction really fast! A far better and more usable situation would be to get one of the better starting cabs out there right now: the Tiptop Mantis. Then put ALL of the modules you have into that to form a complete and MUCH more educational full system. And if you think that a 2 x 104 hp with beefy power is expensive, then...
Intellijel Palette 62 = $299
Tiptop Mantis = $335
Clearly, it makes more sense in the long run to ditch the little skiffs (keep them for other purposes, though) and put your ENTIRE system in the same place, under the same power. This also helps avoid issues involving possible ground loops from having two devices, each with their own P/S, talking to each other and potentially passing a lot of ground loop hum between them.
In truth, if you want a "learning system"...it's free. VCV Rack is a Eurorack emulator that does a VERY good job at behaving like you'd expect the hardware to operate. There's even some modules that replicate familiar ones from MG. https://vcvrack.com/ I'd suggest messing around with this for a while before whipping out the plastic for actual hardware. It does take a good bit of computer power to run it at crazed synth veteran levels, but you should be able to work out how the basics work before your computer says "ENOUGH!" due to the processing load. My suggestion would be to start exploring what VCAs are for and what they do...as there's not a single one in the above build!
The other suggestion is that you should put up a build that contains ALL of your modules. Don't worry about the order in the cab...plenty of us will likely have a lot to say about it and do TO it. Probably a lot more educational in the long run...
