Maybe it is just my ADHD but I can't concentrate with any sort of flashing light in the room.
My friend uses his RGB-lit gaming pc for his home theater and he can happily watch movies and TV with 8 RGB fan lights flashing.
It is beyond bizarre to me.
I got a bunch of RGB fans and components and I just left them on static white since like day two (the case is white as well). Looks clean AF, kind of a portal turret aesthetic.
