Fractal Designes Meshify C has been modified to have a 15.6” Screen built in to the glass door. You can display moving backgrounds as well as any still images. You can also put up your frames per-second or the temps on each component. The limit is your imagination.
The side panel is run by the onboard graphics so it shouldn’t impact gameplay. The side panel is an extended desktop.
I will try to upload a gif so you can see the screen in motion.
