Apparatus, system, and method for toolless installation and removal of an expansion card

A cassette for toolless installation and removal of an expansion card is disclosed. The cassette is provided with a detachable front plate, back plate, and side plate for substantially enclosing an expansion card. The front plate and back plate is pivotally coupled. The back plate includes horizontal and vertical zip slides, allowing the cassette to adjust to expansion cards of various sizes. A chassis is prepared for insertion of the cassette by opening a chassis top plate. The cassette is then be inserted into the chassis from a substantially horizontal approach and secured therein by a cassette coupler. A user then pivots the cassette downward, such that the conductive pins of the expansion card sequentially engage the expansion connector. The chassis top plate is then closed, securing the conductive pins of the expansion card in the expansion connector.
