Those nuts at HardOCP have ripped apart an Xbox 360 and water cooled it — and they say its easy to do!!!
Overall, I am extremely satisfied with our Xbox 360 H20 project. We met most of the goals we set forth four years ago with our original mod, and we are — once again — the first people to water cool an Xbox.

In the end, we set out to water cool an Xbox 360 simply ‘because we could’ but it turned out to be a fantastic venture, and overall a huge benefit to the Xbox 360 cooling. I am sure we will see commercial water cooling kits pop up for the Xbox 360 sooner or later, but this build-out shown here should get you well on your way should you wish to do it yourself.
