A tidy PC interior can improve air circulation, maintenance, and potentially extend the service life of components long-term. The article discusses how to organize a system that includes power supply cables only where they are needed and routing them behind the motherboard tray. The process involves disconnecting the computer from the power supply and rearranging rough cable bundles, removing dust and securing all connections. This tidy arrangement also improves the visual impression of the PC, particularly in systems with glass side panels or RGB lighting.
