Just a light-hearted joke. Yes, though I do prefer the peace of mind of the zero risk involved with air cooling, I'm sure almost nobody will accidentally shatter that glass and splash water all over the inside of their case.
It's just funny to see the stakes raised a little bit. It'd be like reading that using gasoline instead of water results in better cooling, or that you can just put a thick conformal coating over the assembled system and cool it by spraying a garden hose directly at the CPU socket and letting it drizzle onto your graphics cards. At what point does the risk become too great? The line will be different for everyone.
