             :  - DT:   4 RAM slots, PEG, PCIe x1, PCI, PCIe x16
             :  - MT:	 4 RAM slots, PEG, PCIe x1, PCI, PCIe x16
Both of these use the exact same PCB, but the MT version has an extra SATA connector installed on the mainboard. DT has the footprint for the connector, but it is not installed.
