That would be annoying. And real water cooling has to be done with mere demineralized water which transfer heat better, doesn't stain tubings and WBs and is not coductive. Tubings at 90 degrees are plain stupid, 45 degree and swirling Bitspower ones are the best. But yes, you pay for the look of it, if this satisfies people go on. It's like adding neons everywhere and big screens and stereo in your "tuned car", among normal cars it stand out, among race cars it's just a jester.
