3. SUPERMICRO X11DPI-N:

Check on Amazon Check on Newegg

This is also an E-ATX form factor motherboard. Also, some aspects of the layout are different than a standard ATX system, and you might need to make some modifications to complete the assembly. There are plenty of customization options in the BIOS, and we highly recommend to update it to the latest. Also, we recommend using low-profile DDR4 memory, since there are space limitations for DIMMs with taller heatsinks.
