Hello

Nice to meet you. I have a technical question.
I assembly PC. In PC case, I want something very clean, so I twist the power cables like DNA.

I would like to know if it is good or bad? Because I wonder if this create interference. I know that eletricity in rolling cable create magnetic.

Sorry for my english ^_^
Thank you

As far as I know, no problem at all. But you may try using wire holders like this one:
