A portable computer includes a first housing having a first wall defining a first opening and a surface surrounding the opening and having an inside periphery. A first component is removably received within the opening and defines a body with an outer periphery that is inset with respect to the inner periphery of the opening. A first locking member is removably attached within the opening. The first locking member defines an outer periphery extending along the inner periphery of the first opening of the housing. The first locking member also defines a second opening having an inner periphery that is inset with respect to the outer periphery of the first component body such that a portion of the first locking member overlies a first portion of the first component body. A second portion of the first component is exposed within the opening of the first locking member.
