A computer system includes seveal computing areas which are connected to one another by a number of cables. The cables are necessary to carry information from one computing area to another computing area. The cables can be thought of as the information highway between computing areas. The computer system has a first housing which has a frame. The frame includes an elongated hollow corner post that has an opening along the length of the corner post. The hollow portion of the corner post is used as a cable run.The corner post further comprising an exterior surface having a key way therein. A number of cable guides, each having a key that fits within the key way of said elongated corner post, is attached to the corner post. Each cable guide has a two ends. One of said ends is positioned near the opening in the corner post and the other end of said cable guide is positioned near a computing area when the cable guide is positioned within the key way. A cable for interconnecting computing areas within the first housing passes over a cable guide, through the opening in the corner post, into the hollow portion of the corner post, down or up the corner post and out of the opening in the corner post and over another cable guide.
