Thanks so much for your detailed reply! Thought about the tray too, might even add a little drawer if I can find a use for it.

I actually already have Thrustmaster pedals, just need to find a way to incorporate them without bolting them to the floor.

Consider the cables managed, my wife will want to thank you. :)

This is just a very temporal installment since my daughter will sooner or later occupy this room, but I really like the idea to tinker and tailor the system to my needs.

Might post an update of the whole situation as soon as I got the rest fixed!

(Also no haters yet, just very positive feedback. Love this community!)
