Inspired by the "brain in a jar" concept this build is what I spent the last half-year on. It involved a bunch of work with brass and copper, including lots of soldering, which I had never done before. I also had some custom RAM heat spreaders printed from aluminum by PCBWay which I then painfully polished. To tie it all together I also built a fully custom mechanical keyboard in a matching style and painted some of the other peripherals.
