New easy watercooling from Corsair: Nautilus 500
 

The Nautilus 500 consists of an external unit which sits on top of the computer's case, along with a CPU waterblock and retention brackets. Installation of the waterblock doesn't require the removal of the motherboard, which will appeal to both watercooling newbies and those who just can't be bothered faffing about taking their board out.
