Hey I was thinking about shifting over to a sff shuttle, but I didn't want the heat issues(i'm a rabid overclocker, but I'm ready to take it down a notch to a less capable shuttle based system, but I still demand performance). Anyways I was thinking about dropping an Exos onto the top of one of the newer shuttle 939's. My question is would the koolance waterblock for a 6800 fit between the side of the case and the slot? Would the CPU 300watt block fit? Can the system pass through the back, if I dont use any PCI cards? How much bigger is the Exos than the shuttle itself, I've seen way different dimensions online. I want to keep it fairly silent, but very cool(obviously i know its a trade off, but I can hopefully find the medium here. Any one know of any other threads related to water-cooling a recent shuttle SFF?
