Hi I promised some drawings and here are the 1st version fast drawings to see if the ideas are feasible. They are not good looking but to the point. This picture shows the front with the right side being for the water cooling. On top right the reservoir, below that 2are radiators 60 mm deep with 20 mm deep Fans. The boxes with a cross inside are to small depictions of 2 pumps very square is in real life 5 mm x 5 mm and will in real life be 20 x 20 mm. Ratio 1:4. The pumps are likely a minimum of 60-65mm in diameter Behind the reservoir on top is a PSU Left side Motherboard CPU and GPU. Why 2 pumps to keep speed down and thus noise level. * Bonus Info: A few years ago a friend of mine that works with liquid cooling of high voltage circuits told me that every 90 degree bend adds 10% to the resistance in a loop. I haven't tested or made the calculation but I might. Do any of you know about this? Again 1st drawings so be gentle Next picture shows flow directions still from the front. Color green and blue are cool water red is hot. Then comes a picture from the right side. still t see if it it feasible. Next picture shows a muck-up of possible frame and surface. I've rejected this one like a lot of other option. Still it gave me some ideas for new designs. Design change?: The process lead me to test upgrade my design again, to future prof it a bit more if possible. I will redesign the case to hold 2 Power Supply Units (PSU) For this to work I will move the motherboard down on the tray and add extra mounting holes. The old holes stay giving me 2 mounting heights. The new challenge is that the back of the skeleton now needs an option for a replacement plate for the alternative 2nd mounted GPU and thus a motherboard that is mounted lower. Cable and water routes are also changing. This 2nd GPU also makes the case less movable :/ . Checking weight and cost. This redesign also gives an option for a 3rd Radiator of 360 + header 400 mm on top where the original GPU is located ( control of fans is a new challenge) The drawn borders of the case are actual the edge of the skeleton. You have to imagine a 3 mm carbon fiber shell.
