This is my custom water-cooled build in the original Lian Li PC-O11. I decided against colored fluids or any other color accents to make it fully RGB compatible. The white RGB setting looks best on camera in my opinion, but I also like it cycling between blue and yellow or between blue and magenta.
One major design aspect that I came up with in an early stage of planning is moving the pump into the hidden compartment. Not only does that allow for a clean tube routing in the main compartment, but it also makes room for the big glass reservoir from EK. The tubes for the reservoir are hidden behind it, which makes the entire reservoir look like it is floating.
Regarding the components, I decided to give the GPU its own set of two tubes in the front and the monoblock its own set of two tubes in the back. This creates a layered look and lets the eye dive into the scenery. The tubing for the monoblock is also symmetric, which always looks good and avoids any tubes covering the RAM modules. My favorite detail with the tubing is the pass-through next to the mainboard. It looks super clean and creates curiosity for where the tube is going :D
The entire build process took me a whole month from receiving the first parts to filling the loop. Even tough I did precise planning, I had to place additional orders to really get all the fittings, tools, and minor parts that where needed in the end. The build process was a wonderful experience.
