I build it based on an old Aluminum server case that housed previously a Dual Xeon System from 2002. I did build the system under the assumption that no fans would be used within the case. Hence I came up with a cooling solution that cooled everything from the mainboard over the power unit, memory, the hard drives as well as the GFX cards with water. I did buy some coolers and build others myself out of copper pipes. The system holds about 14 liters of water and utilizes 4 car radiator units and a hand build copper pipe grill. I came up with a regulation and refilling system on top of the computer to regulate the water levels. The water is moved by 2 pumps on internal and one external pump that can be added if higher water flows are required. The car radiator units on the side and on the top have 8 silent fans attached to them that can be triggered on a hot summer day to drastically improve the cooling performance by switching from passive to active cooling. I painted the aluminum case with copper color out of esthetic reasons to get an overall look that fits the copper pipes.
The system can run with 100% CPU and GPU load and an air temperature of 25°c with a water temperature of 28°c in passive and 26°c in active cooling mode.
I have 4 monitors attached to the 3 with 1920x1200 and one with 2560x1600. I use this system as my main work PC. I am using the system now for about 5 month without problems, I just had to add about 100 ccm of new water.
