Omnibox BTT HDMI thicker panel

Due to the amount cables that are needed for RPI for USB and Ethernet extended cables, the display cannot be mounted using the original panel as it doesn't have enough room for USB C cable to power it. So I just simply extended the panel to make it thicker in order to make it further away from the body.
