Gigabyte going one round with the X58 chipset by adding crazy amounts of aluminium fins to the Northbridge and having an incredible use of the cooling ability to stay stable under load and over-clocked. The full utilisation of the water block is kind of optional, you can remove the enormous fins and cool it with water alone, but having a water system up and running can be costly and takes time to install into your case, so gigabyte looked into it and made the 3D mercury.
3D mercury is a beautiful case that comes with built in water block and instrument with all the bells and whistles you would ever need to have an over clocking a system. But the package is pretty limited in some uses with no support for cooling a north and south bridge with water-cooling at the same time and the multiple graphics solutions can be restricting. But the CPU is all in the throne seat with all copper heat transfer in the back and front gives a stable and cool solution for high frequency cycles. The space of the case is enough to fit an ATX and an EATX board with its slot packed and all of the wires flying in all over the place but still spacious to move you head around to find a screw in all of the mess. With 6 3.5in drive bays and four 5.21in optical bays and the top will accommodate the water block and the neat water meter and all of the controls with the fan and the refill station right on the top. For the expansion slots in the back a standard 7 slots and two 80mm fans to blow the heat out, but the heat transfer is only going through the front and going to fill the whole space and eventually passes though the back case. But the problem is that this is a fully configured for water-cooling so to use air cooling is not a good idea with this case.
Cooling capabilities of the case is in the high hopes when you think of water and that the help of thermal transfer with water keeps it in 24 degrees in idle but when overclocked the difference of silent, normal and OC settings in load are relevant the OC going 41 degrees cooler helping to keep a hot summer day play in Crysis but never having to have a hang or a crisis in a overheating system. 3d mercury from Gigabyte is a good fully configured water-cooling rig and able to have a EATX board like a skulltrail if you’re still like the concept, they is some flaws with full water-cooling configuration but cool enough to fit any system with ease.

This looks to be a very unique case.
