Once you get into the modding scene or attend a lot of LAN parties; you tend to take notice of your rig a bit more and always give it a sprucing up before the next event. With water cooling and dyes, it seems that the dye will never last forever. It seems that no matter how much you add, if it was old to begin with, it's going to look old after you add more dye. For those that have already figured this out, you know it's time to change the water; a nice big resevoir is just what ya need to make things easy!
