Why So Many Wires???

I cleaned and wiped my computer off and around the desk and behind it.  I unhooked all of the wires and neatly zip tied them together to make it more organized behind my computer but after looking at all of the wires, it barely looks any better.  Well, at least I know that everything is fresh and sanitized for the beginning of the year.  Now if they would just fix the sound on my SMART board, I would be in business.
