The PC building community's obsession with RGB lighting has reached its logical conclusion - putting rainbow lights on a power supply unit fan that literally no one will ever see. It's like wearing designer underwear to a swimming pool - technically impressive but fundamentally pointless.
The RGB PSU joins other engineering marvels like the cup handle that blocks your fingers, a gate that guards absolutely nothing, and whatever that blue watering can abomination is supposed to be. At least when your code fails spectacularly, people can see it. This is just wasting electricity to illuminate the inside of a metal box.
