I did the build about 3 years ago. But the GPU was my old Sapphire r9 380. I decided to upgrade my GPU with RX5700 and I want to publish my build as well.
I choose RX5700 instead of XT version because I want it to run cooler since the SG13 is already lack of good ventilation and I also game with 1080p, so no need for overkill.
To make my build tidy, I did custom cabling with my crimper and aliexpress atx pins. Mostly I just shorten the cables, crimp a new pin and put it back on same plug. I did it one by one so I didn't need to follow a guide or scheme.
