That Vigolix machine looks vaguely similar to what I made already actually.
Not sure what monitor size yet but need much bigger than the 19" I use currently. Something like 27 would be good, although it might be a bit too wide for the location I was going to put it (where the existing one is) and my options are limited.
What I envisage is something along the lines of separate modular monitor and control sections, which can be moved up/down & in/out respectively.
For the monitor this need to be on something like drawer runners, but smoother and more robust, with gas rams (like on a car tailgate) to make it sort of 'neutral weight' (or as close as I could get). That's similar to what I fitted to my CNC machine on the vertical axis. It'd have a drag chain or something for the cabling from it.
The sides of the cabinet itself would extend up to be level with the top of the monitor when in racer mode, but the sides of the monitor module would go down to floor level so that when it's raised to upright mode it still has full length sides to the cabinet.
The seat admittedly is not likely to be a masterpiece of comfort and ergonomics, but would be housed in the lower front part of the upright cabinet, which extends outwards on heavy duty runners, with castors beneath the seat part itself.
The controls would also need to lower down and extend of course, but I've not really given that much thought. It could again be a drawer runner type arrangement which extends down at an angle.
It's all a bit rough in my head but sort of makes sense (to me at least).
It would need a lot of careful measuring and planning though of course, unlike my existing cab, which was a case of "Yeah that looks about the right shape. And if I do it this size then this old wardrobe is a perfect donor", lol!
I'll have to try and knock up something in Sketchup to give a rough idea, then everyone can point out why it won't work. That's not sarcasm btw - I need telling stuff like that in case I don't think of an obvious blunder then get most of the way through it before realising it won't work!
Like I say, I won't be able to try building this for some time anyway unless I want a divorce, and I don't want a divorce ideally. Gives me time to think it out tho
