In the illustrated embodiment, PCI cassette 102 includes housing 110, electronic component 112, output connector 114, and latch mechanism 116. Housing 110 is a mechanical structure that defines much of an external surface of PCI cassette 102 and receives and/or securely stores most of PCI cassette 102 (e.g., electronic component 112). Electronic component 112 is a computing device such as, for example, a central processing unit (CPU), random-access memory (RAM), non-volatile memory, graphics card, input/output interface, and/or network interface. Latch mechanism 116 is a moving assembly (that moves relative to itself and also relative to the housing 110) that is configured to facilitate the insertion and removal of PCI cassette 102 from frame 104. Output connector 114 is communicatively connected to electronic component 112 and is structurally connected to housing 110. Latch mechanism 116 is also securely connected to a terminal end of housing 110. Output connector 114 is configured to engage with an input connector 108, and latch mechanism 116 is configured to engage with a lug 106. Thereby, PCI cassette 102 can be inserted into CSCB 100 and secured by latch mechanism 116. Furthermore, electronic component 112 can be communicatively connected to CSCB 100.
