Gigabyte MZ73-LM0 Rev 2.0 Schematic
For storage, there is a single M.2 drive (ideal for the operating system) and two MCIO ports which can connect to either U.2 or SATA drives as needed. External connectivity is also somewhat limited, with just two rear USB ports, two RJ45 10Gb Ethernet ports, and a third RJ45 for remote management... oh, and a serial port.
The limited number of connectivity options on this motherboard shows it was probably designed with servers in mind, but we are able to fit it in a tower workstation chassis with fairly quiet liquid-cooling for the CPUs - providing a tremendous amount of CPU power and memory bandwidth at your desk, if your work can utilize it!
