Cable clutter, solved: a small-desk plan that does not require drilling.
The goal is not to hide every cable. It is to make the cables you need follow one predictable route, with slack only where equipment has to move.
Map every connection first
Unplug nothing yet. Photograph the current setup, then list which leads need to reach the wall, which connect devices to each other, and which move with a laptop or standing converter. This prevents an attractive cable bundle that is impossible to service.
Build from the power source outward
Mount or place the power strip near the rear of the desk. Collect low-voltage adapters in a cable tray or box, then route one bundled line toward the outlet. Use reusable hook-and-loop ties rather than permanent zip ties; you will eventually change something.
Leave a service loop
Give a movable monitor or laptop a small, intentional loop. Everything else can be shorter and tighter. Label power bricks on the underside with removable tape so you can identify the right one without crawling under the desk.
