The DTX: MotherBoard format is 8" wide x 9.6"
deep (203.20mm x 243.84mm).
While the Mini-DTX format is 8" wide x 6.7" deep (203.20mm x 170.18mm).
The DTX main-board is one of a number of Small Form Factor [SFF] mother-boards.
Both DTX motherboard formats are smaller than an
ATX Mother Board and will fit into an ATX Chassis.
However, the chassis would need to accept the DTX mother board.
The DTX motherboard will accept one PCI connector, and one PCI Express connector.
Refer to the manufacturers page for Power Supplies to find compatible case supplies.
The Power Supply will
indicate the standard which they comply to, in this case the notation
ATX12V indicates the power supply compiles with these pinout tables.
Pin out tables for DTX connectors are listed below.
The DTX pinout is really a group of dual pin headers located on the Mother board.

Memory Module formats and manufacturers are listed on the Memory Module Manufacturers page.
List of Computers Manufacturers
A few computer manufacturers may use non-standard or
proprietary components in their systems to reduce costs.
The pinout for the power headers
listed on this page comply with the ATX specification. However some
companies may use pinouts that differ from the pin out tables above.
First try to determine the pin out of the headers listed above from the manual
that shipped with the computer, and use these tables only after checking
the manufacturing sources of data.
