Riser cage half turn fastener
A riser cage of a computing device comprises a bracket, a riser card attached to the bracket, and a fastener attached to the bracket. The bracket is to support an expansion card. The riser card is to electrically connect the expansion card to the computing device. The fastener is to secure the riser cage to the computing device. The fastener comprises a handle, a shaft extending along a first axis, a pivot connecting the handle to the shaft, and a half-turn latch coupled to the shaft. The half-turn latch is configured to engage with a receptacle of the computing device to selectively secure the fastener to the receptacle. The handle is pivotable about the pivot between a deployed configuration and a stowed configuration, and in the stowed configuration the handle is parallel to the riser card.
