Yes, but you already said bling. Mind you I guess you could turn the LEDs off. The annoying part is that no matter what you are paying for the LEDs, even if you don't want them.
It's just me I guess. I've been on Alienware cases since 2008 and they have always had RGB LEDs. The only time I change mine now is when I switch hardware haha. My Fury X rig is all red LEDs ATM and my main rig is set to Fallout 4 colours (well, Vault Tec blue and yellow

)
So I do still play with them from time to time but not much. What I would like to see, though, from RGB is proper interactive gaming with them. It seems they haven't quite reached the Alienware stage yet, but the whole case is active on an AW. Few examples.. In Metro (both 2033 and LL) when you turn the flash light on the case lights turn white. When you are dying they all turn red. If you enter radioactivity they all glow green, and so on. It also does it in Dying Light and a few other games. If you fall from a great height they flash red as you land. If you are dying they turn off, and so on. It's cool because it adds ambience.
So I suppose in about two years time when that actually becomes a thing on RGB desktops I may sit up and pay attention
