I don’t know what happened, but I put together a PC for the first time in some years, and holy mother of God, everything has RGB LEDs slapped on them now. I had to actively work to find parts that didn’t have RGB LEDs on them (and I still accidentally wound up with it on the motherboard). I mean, yeah, LED case fans have been a thing for a while, and there was always a contingent that put electroluminescent strips on their computers. And it kinda grew into a lot of keyboards and mice. But now it’s a large portion of CPU fans, most cases, RAM sticks have RGB LEDs, motherboards have RGB LEDs. I didn’t have trouble finding non-RGB LED NVMe storage, or non-RGB LED SATA drives, but even there, you can get them. Hell, there are RGB LED cables.

I can only assume that a large portion of the people building PCs these days are doing it to have them physically blinged up.
