grid pattern

Hello. As in the title, I wonder which mesh patterns you like in Mesh PC cases. For example, which patterns such as honeycomb, circles, triangles fit your style? Thank you for your answers.

So when I use or not use my desktop a "while" (such as just leave it there turn on/using it around 30 min or 1 hour later~) my desktops intent will go really slow! if I restart it.. it will goes back to normal again.. and after 30min or 1 hours later .. it goes slow again ... can anyone help...
