Intel's NLX design, introduced in 1997, is an improvement on the LPX design for low-profile systems, with an emphasis on ease of maintenance. The NLX format is smaller, typically 8.8" wide and 13" long, so well suited for low-profile desktop c All expansion slots, power cables and peripher connectors are located on an edge-mounted riserca allowing simple removal of the main motherbor which is mounted on rails in the chassis. It u full-width I/O shield to allow for differe combinations of rear-panel I/O. The design allo for use of an AGP card, but the slot must be on IT motherboard, which reduces the ease of maintenan when such a card is implemented.
