➀ A keyboard enthusiast built a custom 13-inch laptop using Framework 13 components, replacing its membrane keyboard with a low-profile mechanical KL Chalk switch design for superior typing feedback;
➁ The DIY project involved designing a scratch-built aluminum chassis, custom PCB, and rotary dials for volume/brightness control, along with an integrated USB hub (which initially failed);
➂ Demonstrates the potential of modular laptops for extreme customization, though requiring advanced machining and electronics skills.
