Why are so many gaming parts made with annoying leds? I wouldn't mind having a case with a transparent window in order to quickly check if said computer needs a cleanup but those lights are so annoying this is a no go.

I could disable most leds from my mainboard settings but not for my gpu. I can turn off the lights of my cheap mechanical keyboard with a shortcut but they always turn on by default when I turn the computer.

Is there a database of parts without stupid lights included by default? It should be the norm but it seems it has become rare or you have to pay a premium or install conpanion apps to be able to turn them off by default..
