My gaming pc lives in a soundproof cupboard 5m away without a case because quietness is more important to me than any visual element, so any RGB thing gets avoided, or turned off.
I can appreciate a very colour coordinated and well put together "gaming" computer in a purely aesthetic sense. Some are genuinely pretty and I get that some folk take a lot of pleasure out of making something that looks beautiful and best of luck to them. But I'm not one of them.
