No idea how I've never seen this thread but oh well! Here I am. I've been doing WCing for a long time now; first WC rig was back in 2007.
In more recent times, I switched to hard tubing in 2021 and did a whole new build.
My many times updated/modified, old school soft tubing rig and a 3090 FTW3:
I purchased a whole new rig to build alongside this one (excluding PSU), and then plotted out the new loop on a whiteboard. I couldn't do the 480 rad at the front with the fittings down low as the case didn't allow the bottom radiator to be mounted far enough back, sadly.
Here are some images of pieceing the loop together, with a Radeon 6870. I kept switching between various cards at the time, and hadn't decided on one to keep. I eventually settled on an MSI 3090 Suprim.
My very first bend of hard tubing:
Worst pipe to do in the whole rig and I got it first try somehow:
Finished loop in phase 1 with no GPU:
Adding the 3090 Suprim into the loop:
Phase 2 completed. I partially added the fill and drain loops here. I wouldn't end up adding them on until 18 months later. Whoops.
Eventually, I added the missing fill and drain portions of the loop.
I then upgraded to a new board, CPU and fresh block Oct last year. I took no pictures of this process other than the end result, I'm afraid! Even then it's not a good picture to boot.
