People tend to do things themselves because it is cheaper then hiring an outside source because they not only charge you for the parts, they also charge you for installation, labor and service fees. That could very well add up to a pretty penny. If you are thinking about wiring your home for entertainment purposes then you may need to invest in some patch panels. They tend to be perfect for small office or home networks, and best of all you don’t have to pay anyone to come out and install it for you!
