Specifications

Computer Architecture and Maintenance (G-Scheme-2014)
Not all motherboards are the same physical size. The most common size is ATX;
however, the specification which created the ATX standard also provided for several
alternate configurations. All ATX motherboards will have the same general
configuration, with the major components located in the same places. While it is
usually possible to mount a smaller motherboard into a computer case, mounting a
larger one may be impossible.
A second motherboard configuration standard called "BTX" was created by Intel at a
later time, in an attempt to solve airflow problems with the original ATX standard.
However, this standard never caught on. While there are some BTX motherboards on
the market, especially proprietary ones made by major computer manufacturers, they
are not all that common.
The DTX standard was created by AMD as an answer to Intel’s failed BTX standard.
