Cases, stands, racks - physical setup questions

[Frank1119]

I’m a guitarist, so a different use case.
I did this:

My wife got tired from carrying around gear

So, because my wife got tired from carrying around gear, I built this: With wheels: [IMG_1809] The back. The silver box in the middle is the Geekom AE7 mini pc: [IMG_1810] The front, including some USB connectors and a Behringer UMC1820: [IMG_1811] And a drawer to stash a way a small keyboard and a touch screen. [IMG_1812] This drawer is also helpful to reach the inputs at the back, if I need these. 16 Kg in weights, but luckily, as I mentioned above, there are wheels.
