About to go 939, will be overclocking, was thinking of going with an xp-120, but now I am seriously considering water. My problem is, I live in NY, go to School in Boston and move the machine back and forth a couple of times a year, are there any water cooling systems that could handle trips like that without being completely emptied and refilled? I know tomshardware had a prototype for Prescott that was completely self contained (you couldn?t empty it if you wanted to) so something like that could work. Any suggestions, or should I just stick with air until I can keep the machine in one place for long periods of time?
