Riser Card
A riser card is normally used in a low profile case. Instead of the cards being perpendicular to the board, a riser card is used to make them parallel to the board, saving on the height. The riser card (short) is inserted to the mainboard perpendicular and the the others are inserted into the riser parallel to the main board.
