Thus far, motherboards have remained pretty stable in terms of size, shape, and the location of cable connectors and such. Long ago, the AT standard morphed into ATX, the current day standard which outlines exactly where components are located on a board. The ATX 2.0 standard (the second revision of ATX) made way for a small assortment of sizes like Micro-ATX, Flex-ATX and so forth. Yet, no matter what the size of the motherboard, whether it be for a small form factor PC, or a desktop PC, the location of components like PCI slots, processor, and I/O ports (PS/2, USB, network, parallel, and serial) are all essentially the same. Several months ago consumers found out that Intel had plans to change all this. Called BTX, this new standard is as yet unapplied, but will eventually force you to toss out all your good hardware and purchase new parts; at the very least a case, motherboard and power supply which conform to the standard.
