Have you ever been told you need to lighten up? Depending on your interpretation, you can do exactly that with Asus' new ROG Aura Terminal, a standalone RGB lighting control box that supports a whole bunch of LEDs.

It's a four-port controller, each of which supports up to 90 LEDs max, and a total of 210 LEDs throughout. The math doesn't add up there, so if utilizing all four channels, you can't have all of them beaming 90 LEDs.
