This is a build of parts that I already had (Case, CPU, RAM, SSD, PSU), parts I got second hand (GPU + block, radiator, pumpres, fittings) and some new parts to complete the build (CPU block, tubing). You'll find this build very unbalanced, the CPU is a bottleneck and doesn't really require watercooling at all, but the build was just an exercise to build my first ever custom loop.
