NLX (New Low Profile Extended) was a form factor proposed by Intel and developed jointly with IBM, DEC, and other vendors for low profile, low cost, mass-marketed retail PCs. Mini-ITX is a 17 x 17 cm (or 693 x 693 Inches) low-power Motherboard Form factor developed by VIA Technologies. Embedded Platform for Industrial Computing (EPIC is a computer Form factor standard put forth by a combined effort from WinSystems VersaLogic Octagon Systems Micro/sys Nano-ITX is a computer Motherboard form factor first proposed by VIA Technologies at CeBIT in March 2003, and implemented in late 2005 COM Express, a Computer-on-module (COM form factor is a highly integrated and compact PC that can be used in a design application much like an integrated circuit ETX, standing for Embedded Technology eXtended, is a highly integrated and compact (3 ETX, standing for Embedded Technology eXtended, is a highly integrated and compact (3 Pico-ITX is a PC Motherboard form factor announced by VIA Technologies in January 2007 and demonstrated later the same year at CeBIT. PC/104 (or PC104) is an Embedded computer standard controlled by the PC/104 Consortium which defines both a Form factor Mobile-ITX is the smallest x86 compliant Motherboard Form factor. International Business Machines Corporation abbreviated IBM and nicknamed "Big Blue", is a multinational Computer Technology Digital Equipment Corporation was a pioneering American company in the Computer industry Release 1. 2 was finalized in March 1997 and release 1. 8 was finalized in April 1999. NLX was similar in overall design to LPX, including a riser card and a low-profile slimline case. LPX (Low Profile eXtension originally developed by Western Digital was a loosely defined Motherboard format ( Form factor) widely used in the 1990s It was modernized and updated to allow support for the latest technologies while keeping costs down and fixing the main problems with LPX. LPX (Low Profile eXtension originally developed by Western Digital was a loosely defined Motherboard format ( Form factor) widely used in the 1990s
Many slimline systems that were formerly designed to fit the LPX form factor were modified to fit NLX. NLX is a true standard, unlike LPX, making interchangeability of components easier than it was for the older form factor. IBM, Gateway, and NEC produced a fair number of NLX computers in the late 1990s, primarily for Socket 370 (Pentium II-III and Celeron), but NLX never enjoyed the widespread acceptance that LPX had. Gateway Incorporated is a Computer hardware company based in Irvine, California, which develops manufactures supports and markets a wide range of is a Japanese multinational IT company headquartered in Minato Tokyo, Japan. Socket 370 (also known as the PGA370 socket) is a common format of CPU socket first used by Intel for Pentium III and Celeron Most importantly, one of the largest PC manufacturers, Dell decided against using NLX and created their own proprietary motherboards for use in their slimline systems. The multinational technology company Dell Inc develops manufactures sells and supports Personal computers and other computer-related products Although many of these computers and motherboards are still available secondhand, new production has essentially ceased, and in the slimline and small form factor market, NLX has been superseded by the Micro-ATX, FlexATX, and Mini-ITX form factors. microATX, also known as µATX (sometimes Transliterated as mATX or uATX on Online forums is a Small form factor standard FlexATX is a PC motherboard Form factor derived from ATX. The specification was released in 1999 by Intel as an addendum to the MicroATX Mini-ITX is a 17 x 17 cm (or 693 x 693 Inches) low-power Motherboard Form factor developed by VIA Technologies.
