Hi,
In several of the questions on your site, I have seen your staff instructing people to use distilled water without any additives as their coolant. While distilled water may seem like a "safe" choice of coolant (humans can drink it, it must be fine) this is simply not the case when considering a watercooling system. Distilled water without any corrosion inhibitor additives will rapidly degrade metals, especially in mixed metal systems, and it will very easily harbor all kinds of bacterial growth if no biocidal agent is added. I think you are misleading a lot of your customers who are new to watercooling, and potentially causing them to need to replace their entire water loop down the line.
