Configurable computer chassis port and method of manufacture therefor

A personal computer (PC), comprising:

• an external data input device;
• an external data output device;
• and
• electronic data processing circuitry contained within a main chassis and removably couplable to said external data input and output devices, a wall of said main chassis having a substantially planar portion, said substantially planar portion having a first port therethrough of first predetermined dimensions, said first predetermined dimensions corresponding to external dimensions of a first electrical connector, a partially-sheared punchout section defined in said substantially planar portion of said chassis wall, said punchout section removably coupled to said chassis wall and having an edge contiguous with said first port, said edge forming a portion of a perimeter of said first port and substantially coplanar with said substantially planar portion of said chassis wall, said punchout section selectably removable to create an aperture through said chassis wall, said first port and said aperture cooperating to form a second port through said chassis wall of second predetermined dimensions, said second predetermined dimensions corresponding to external dimensions of a second electrical connector, said punchout section thereby yielding a port selectably configurable to accept electrical connectors of different dimension therethrough to allow said electronic data processing circuitry to be coupled to a one of said external data input and output devices.
