Who actually uses water cooling grommets?

This blog post stems from a conversation Clive and I had the other day about the water cooling grommets we’re seeing on most cases these days. If you’re not sure what I’m on about a water cooling grommet is a rubber-lined, circular cut-out in the back of a case that appears to be designed to have water cooling tubing passed through it.

The crux of the conversation was essentially the question of whether anyone actually uses these grommets, and if they could actually be considered a feature when it comes to calculating a case's feature score in a review. My argument is that they shouldn't be counted and I’ll explain why.
