Low Profile Extended (LPX) and New Low profile eXtended (NLX) are motherboard form factors known for the usage of a riser card (daughterboard) inserted into a slot near the edge of the board. The main advantage of this type of design is that expansion cards that plug into a riser card on the LPX/NLX motherboard are parallel with the board which saves space and allows for a smaller system case.
