I'm soo exited ! 😄

can you sync/control the LED without using the button on the case?

As today most gpus are open shrouds and exhaust from the side of the card inside the case unlike in your video there, bottom fan is choked by hdds and wires from psu there so theres very limited air flow on that fan, its useless. That kinda case layout has been avaible for years and its not even optimal, its gpu that produces most of the heat in the case not cpu and it has been like this for decate, place gpu so it can have 3 or 2 exhausfan close to it from where it pushes out thermal load then you have something new.
