If a Corsair LCLC leaks, just make them buy you a new system.
While this might be a best-case scenario, they won't do it. They will do everything in their power to place the blame for any failure onto the user since they opened the box, installed it and then had the failure. As far as they are concerned, if it left the factory in the box, it's pristine. Any failures would the be due to 'operator error', even though in reality this isn't the case. If you wanted to be really safe, go with a hardware vendor like EVGA who will replace via RMA just about anything they sell for any reason. I killed a video card due to my own mistake during a watercooling mishap and they gladly replaced the card. You need to ensure you register the components within 30 days of purchase for this to be possible, mind you.
