Thanks Jim, that's exactly what I was looking for.
As for the rack solution, it was a matter of using that spare 12U I already have. I'm just thinking long term. I'm not planning to stock it all up with modules anytime soon.
The multiple warts and extra HPs really don't bother me. I use multi-ways for everything. And I find it's a fair trade-off to avoid the ridiculously overpriced cases out there. After some research at Thomann, I found it to be the best solution for me, considering not only price per hp, but space distribution in my studio.
