Custom PC
I am by no means the first person to build their own computer, let alone an engineer doing so. However, I went all out with this build. My theme when picking parts was the 2nd best. 2nd best graphics card, 2nd best CPU, 2nd best SSD, you get the idea. For cooling, I made a custom water loop with rigid tubing. Bending and shaping the tube runs was a lot of fun, and definetely a learning experience.
