Corsair Nautilus 500 Tested
 

The Corsair Nautilus500 is the simplest watercooling system we've come across. The external, all-in-one nature, carried on over from the HydroCool series, means that you don't have to mix and match parts; the hard work is done for you. Multi-platform support is also present, as is the opportunity of adding in GPU and northbridge blocks at a later date.
