NLX is an industry-wide open specification for a space-saving computer motherboard . The NLX specification defines the motherboard size, hole mounting locations, riser card location, and maximum component heights on motherboard. Companies such as IBM, Hewlett-Packard, Digital Equipment, Sony, NEC, Toshiba, Gateway, and Fujitsu support NLX.
Traditionally a computer technician had to open the computer case using tools, but an NLX case is tool-free. Another feature of the NLX specification is the motherboard itself. It rests on rails and simply slides out without any screws to unscrew or card to remove. The motherboard plugs into a riser card that sits at a 90-degree angle from the motherboard. A riser card is an expansion card that physically extends a slot for more expansion cards. When the motherboard is removed, the riser card stays in place. This allows a technician to replace a motherboard or upgrade a component on the motherboard in about 30 minutes instead of the usual two hours, saving the customer money.
NLX motherboards support current and future processor technologies, the Accelerated Graphics Port (AGP), and tall memory technology. NLX is beneficial because it improves access to components, supports new technology, and lowers the cost of ownership.
