OK guys.
You may take this post as a joke, and in part it is a joke indeed - on message board where half of the users own sim rigs worth tens of thousands of dollars it can't be different.
But in the same time I think it's not a terrible idea to show something what casual players, not so much devoted to sim-racing and not so skilled, can use... at least I'm planning to use.
I admit that I'm quite happy with what I was able to achieve without any tools (except one ring wrench, one screwdriver and one allen wrench), by assembling a few flat and angle bars together using some screws, nuts, washers and a piece of duble-side 3M tape. Honestly, I'm extremely lucky that all these basic, non-custom parts found in the nearest DIY store (and one cheapest magnetic phone holder from Amazon) suit so well to my "project" (what an exaggeration!) and their dimensions fit perfectly. And thank god that my wheel-stand mounting plate had some free space to RIG everything!
I was a bit afraid that really stiff and thick USB hub cable would ruin all my plan, but fortunately it folds in the correct direction to plug it into my PC's front panel socket. (what a relief!).
Oh, and do you all see that intricate, elegant cable management?
OK, no more jokes, I'm really pleased with what I've managed to do with such a low budget and low expectations.
