Gigabyte MZ73-LM0 Rev 2.0 Picture 83523
The Gigabyte MZ73-LM0 is a large SSI EEB motherboard, the majority of which is dedicated to housing two AMD EPYC 9004 series processors and their accompanying 24 DIMM slots. Because so much space is needed for those, there are only four PCI-Express x16 slots - greatly limiting GPU and expansion card options. Onboard ASpeed graphics with a VGA output is present, though, so some use cases may not need a dedicated GPU at all.

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.

William George (Marketing Project Manager) Says:
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!
