No more details are known. Just that some cables catched fire. Maybe they examined one of the returned ones and found out that they were not manufactured to spec or maybe the contractor reduced safety margins to a point where they become potentially dangerous. I don't think any company wants to be responsible in case someone dies.

Better to collect all the cables before more bad publicity gets generated.

Plus (other comment) most just throw away a cable if it smells funny so actualy numbers are sort of a gray area.

I like small boxes. I built myself a cube sized (Cooltek Coolcube Mini) PC with an (desktop) AMD APU on an Mini-ITX board. There is room for a PCIe graphics card, but the integrated one suffices for the moment. The difference? It is upgradable. Granted, sort of until the CPU socket changes.

But how long will all these "mini gaming rigs" last? Probably a year then they end up in the closet. Sure, it works nicely for the manufacturers. You're supposed to replace them every other year. And this in times where even gaming PCs seem to last forever. Sandy bridge intels with a new graphics card and you're good to go for almost everything.
