Mechanical keyboards are a favorite among enthusiasts for their tactile feedback, durability, and customization options. However, building a high-quality mechanical keyboard can sometimes seem expensive. Fortunately, there are several ways to assemble a great keyboard for under $100. This guide highlights some of the best budget-friendly builds perfect for enthusiasts looking to upgrade without breaking the bank.

Why Choose a Custom Mechanical Keyboard?

Custom mechanical keyboards offer personalized layouts, switch types, and keycap styles. They also provide a better typing experience compared to many pre-built options. Building your own keyboard allows you to select components that match your preferences and budget, making it a rewarding project for hobbyists and newcomers alike.

Essential Components for a Budget Build

  • Keyboard case: The outer shell that houses all components.
  • PCB (Printed Circuit Board): The electronic board that registers key presses.
  • Switches: Mechanical parts under each keycap that provide tactile feedback.
  • Keycaps: The visible top part of each key.
  • Stabilizers: Support larger keys like spacebar and Enter.
  • Optional: Lubricants and tools: For smoother switch operation and assembly.
