I dunno, the massive holes in it look really horrid to me. I don't know why anyone would want to do that to their system. Isn't there a better way to cool it without ripping the thing apart? (Maybe just buying an external usb fan or laptop cooling mat or something like that?)Let alone the issues of putting water/liquids that close to the delicate parts of the system. One leak and blam, system is gone.So I suppose if it works and he doesn't mind the looks and risk of it, thats fine for him. But I won't be doing that to either of our PS3's. (We have a slim and a fat one, though the fat one went YLoD on us so it's currently in the shop.)
