YES... I have an old computer that I use just for connecting my site. I do not surf anywhere else with it or use it for anything else. It's basically stripped down with only on board video (VGA), an old network card, no sound card, no hard drive, and only a DVD drive with 4gb of ram.
I boot up, I connect to my site, and then I shut down. Nothing else.
We also have no ads on our site.
