    • Extra ports may be needed for external devices such as printers, webcams, Wi-Fi adapters and even gaming peripherals.
    • Additional ports for microphones, cameras, and capture devices may be required for streaming setups.
  • Laptops vs. Desktops
    • Desktops: Most well spec’d ATX motherboards will come with 6-8 ports.
