A few on OCN have modded the LEDs on the Titan for different colours. Not something I would do personally but it seemed easy enough.
I love the image Kaap put up with the green led fan. I hope that is actually part of it, as with my reverse case, that looks pretty cool and I would see it.
Yeah I saw that man. Looks a bit uncomfortable though. My biggest issue is I bought bloody Palits and they don't allow cooler removal. So I either void my warranty or leave them green

At least with the Krakens I can slyly slice off the warranty sticker and poss put it back with some superglue
