I?m on vacation and just acquired a new Koolance case from a friend of mine. However now I need to transport it back to my home, which is about 800 miles away. I will most likely ship it via courier (UPS, Canada Post). The system has been completed, with the CPU block hooked up and water in the system. I unfortunately only have the case, no spare water additives. I would like to know should I drain the water out of the system before transport? Or is it safe to transport with the water in it?
