Users looking to build their own dual EPYC workstation or system, using completely off-the-shelf components, do not have a lot of options. Users can buy most of the CPUs at retail or at OEM, as well as memory, a chassis, power supplies, coolers, add-in cards. But the one item where there isn’t a lot of competition for these sorts of builds is in the motherboard. Unless you go down the route of buying a server on rails with a motherboard already fitted, there are very limited dual EPYC motherboard options for users to just purchase. So few in fact, that there are only two, both from Supermicro, and both are called the H11DSi. One variant has gigabit Ethernet, the other has 10 gigabit Ethernet.
