I bought a ton of RGB stuff cause I thought it was neat back in the day, then realized most of it is just annoying. Now I put it to use instead. Color coded keys on the keyboard (All alphabet keys one color, all punctuation a slightly different color, etc.), and and rgb light on my mobo that's tied to my GPU temp.
30c: cyan
50c: green
60c: yellow
75c: red
Makes it easy to have a general idea of my temps when playing games.
