Fractal Design R5 - clean strip and trial on up panel on moduvent cover

[worry]

Hello. Just asking. Is this maybe relating to voltage or electricity ?

Few days ago i saw ago on my Fractal Design 5 ( which is very dusty ) an clean strip and trial ,on up panel on moduvent cover.

 

There are many dust on my case on up panel on moduvent cover. But…i dont know why some day i saw on moduvent covers a dash,like somebody touched case or cleaned . But like i said i dont touch case, dust in this place dissapeared itself.

A dash and clean strip on the dusty case, as if someone had dragged a pencil's eraser end or a finger across it, and now i am wondering if the strip and dash could possibly have appeared by itself and not caused by someone or something, as if by magic.  Is this maybe relating to voltage or electricity ?

I dont have any extra added vents in case. Only gpu and cpu fan. Thats all. I swear i dont touch case and my mother dont touch too. Please explain me . Thanks.

Sounds like static electricity attracting dust onto the case, nothing to worry about just wipe it down every so often.
