It's a hot case man.
You look at it and yo usee a v1000 with a little LED meter on top of it with 2 fans.
you see no visual evidence, other than the resevoir on the top, of water cooling. The little you do see is quite rewarding though as the resevoir window lights the room with a vibrant neon blue glow.
IT cools very well after all ti's an Exos 2 cooling system. It's very quiet and you can adjust the fans to however high or low you want the temperature. They also come with 3 thermostats that you put on the Cpu(underneath the heatsink) to enabl ean "auto" setting for the fans so they will not blow as hard when the temp is within the ballpark range you set.
It's expensive but you pay for mostly the intergration. No external pipes whatsoever, you can only see when you open it.
