The GX700 and GX800 are both designed and sold with the water cooling dock and they have slight different connections between them. The water cooling dock will only work with those two models and it is not sold separately. This is because it is not just the dock that is needed, however special connectors and different cooling solution used inside the laptop itself in order to work with the water cooling dock. We hope this information helps. All the best - ASUS ROG Australia
