Maybe this is a bit off topic but how do you like the ergonomics of the two RackBrutes?
Both horizontal and vertical positions have pros and cons:
Horizontal pros: right underneath your fingers, supports cables, headphones, and coffee cups
Horizontal cons: looking at it from an angle, gathers dust more quickly
Vertical pros: better visibility, less desk space, can use it as a phone stand
Vertical cons: slightly more effort to reach
The benefit of combining both a horizontal and a vertical case is that I only need short cables to connect lower modules to upper modules. The added benefit of the Rackbrute is that it can be folded up for transport.
If you're starting out, I'd recommend getting a vertical setup first. It looks nicer and takes up less space. I've always admired the no-nonsense stackable Doepfer cases for that purpose 👍
