I was looking into getting some RGB-lighted fans for my desktop, but then I saw how they were installed and decided to pass. While RGB stuff looks great, they add a bunch of wires and need dedicated software to customize their appearance, which can be a pain if you buy stuff from a variety of brands (Razer, Corsair, MSI, etc.).
I’d like to see a new universal RGB standard baked into motherboards that would control all the RGB lights for both on-board hardware and external peripherals, regardless of the manufacturer.
