1. Plan Before You Plug Before installing anything, look at your case’s cable routing cutouts, tie-down points, and PSU shroud space. Pre-route major cables (24-pin, CPU 8-pin, GPU) behind the motherboard tray before fully securing components. It’s much easier to manage cables when the case isn’t crowded. 2. Route Along Edges If Possible, Not Across Open Space Cables should follow straight lines along the case edges and through grommets - never diagonally across the motherboard. Clean vertical and horizontal runs look intentional. Use the closest routing hole to the connector so the visible portion of the cable is as short as possible. 3. Separate Thick and Thin Cables Run bulky cables (24-pin, PCIe, EPS) in their own paths. Bundle smaller cables (front panel, fan cables, RGB leads) together using Velcro. Keeping cable types grouped prevents bulges behind the motherboard tray and makes troubleshooting easier later. 4. Use the Right Fasteners (Don’t Over-Tighten) Velcro straps ar...
