I am also waiting to get one of these. I have a D5 Next, which I love. I use it to control 10 fans (I have a 1080 radiator with 9 fans, and then I have 1 internal case fan connected as well). The built in SATA powered fan controller is a total god-send as my motherboard is terrible and has 2 fan headers. My experience with the D5 Next has led me to get an AquaComputer UltiTop reservoir from OC.uk (due tomorrow), and I am waiting for the Next High Flow to come into stock. I can be patient, as I don't really NEED it, but it is just such a beautiful piece of kit that I want to have it mounted to the top of my external 1080 radiator.
