My cable box Protips:

1: use transparent boxes like an 11l IKEA Samla so you can easily see what you have.

2: fold each cable in half or a few times more and apply the granny knot[1], this will prevent your cables becoming an entangles mess. There are superior(tm) ways to fold cables, but doing the granny knot for household cables seems the way to go. Doing festivals with retro gaming computers I’ve done this thousands of times and it’s fast, saves space, gives quick and reliable access and prevents damage by pulling on cables from clutter etc

3: use multiple boxes for different categories: audio, game computers, standard power cables, pc cables (sata, usb), power bricks and so on to have some sort of a system, any system will work

4: don’t keep an inventory list: let the anarchy that is you, your memory and family, add and take away cables ad hoc. You will forget what is in the box and that is fine.

5: don’t forget the box exists and look in the box :)
