The schema is based on these excellent instructions by Lb_20. Check out her other very well-documented projects!
I added a kill switch to the 12v live wire and replaced R1, R2, and R3 with the ones I found. The values don't align, one of them is actually a 20k and another is a 12k resistor but since they basically work as voltage dividers it doesn't really matter.
I designed a 3D printable case with two mounting screws to attach it to my shelf and hid the LED strips in aluminum tubes with milky glass for decent diffusion.
Super Happy how it turned out

Interesting recycling of this box.
I've never seen a contrast / brightness, etc. control panel like this, and it gives me an idea for my thelightherder.com project. Controls like this would allow for being able to see at a glance the state of the different parameters, unlike the control knobs, which spin forever. I don't know if something like this exists for HD monitors - maybe something that could be created?
