Challenge: come up with categories for the boxes such that every item has exactly one box that is correct for it.

I've got "USB", "AV" and "Networking & PC Accessories", which obviously has enormous overlap, but equally divides the cables I have pretty nicely.

My boxes been sorted by "what does the cable carry", one power cables, one data, one video, one patch cables, then some are split out, like sound production related cables, one with balanced 1/4", one unbalanced, one MIDI... I think in total 8 moving boxes by now.

It's always a miniature war with my wife trying to optimize all my cables away and me trying to keep as many as possible.

Depends on how big that box is

I have one for video cables, one for audio cables, one for computer gear. Does that make me serious our mildly interested?

For real, I have like 200 kilos of cables. I could very likely reduce that down to something less severe, but that involves sorting and inventorying 200 kilos of cables.
