well i got the aquarius III. the chances of you spilling water on ur system IS VERY VERY SLIM! If you just follow the directions right.. It will work. 1 thing though. Dont use the rubber washers they give u with the kit. Make ur own or get some rubber washers. There too small and if u have a nut that touches ur mobo.. it will short out the mobo. I actully modded my aquarius III. I added a extra radiator in it, i added a extra fan in it, and im running antifreeze in it now. Next week somtime im getting this from this guy. What it is, is a compressor. It will make the antifreeze in it about 0-30 degrees F.
