It that a desktop? Placing a desktop on a floor will see more dust drawn into an atx case more then anything. Most cases will see little circular pads on the bottom whether rubber or some plastic more common to avoid scratches made to the floor itself. Leaving a laptop on the floor however is an invitation for someone to kick it and then realizing it is there.
My desktop is on the hard wood floor. I have to vacuum it out every week because of pets and dust. It sucks, I worry that it will start a fire or blow my PC.![]()
It's a desktop. I put a laptop cooling mat under it if it makes any difference
