For those of you interested in AMD's open industry standard specification should head on over the DTXPC website and download the .PDF. With the specification finally published, it is up to manufacturers to build cases and motherboards based on the specification. Base DTX motherboard specifications are as follows:
- Overall size: DTX 9.60 in x 8.00 in (243.84 mm x 203.20 mm) / Mini-DTX 6.70 in x 8.00 in (170.18 mm x 203.20 mm)
- Mounting hole locations
- Rear I/O dimensions and locations
- PCI and/or PCI Express connector locations

Although DTX is slightly larger than VIA's mini-ITX form factor, DTX calls for two expansion slots. Motherboard manufacturers are free to decide the configuration of the expansion slots, which can be PCI, PCIe or both. DTX motherboards will receive power via 24-pin power connector and auxiliary +12v 4-pin connector as standard ATX motherboards too.
