Asrock released a mini ITX motherboard with server-grade specs. The ASRock rack is known for making good expensive motherboards for workstations and server solutions.
This time I will talk about the Asrock EPC621D4I-2M, it’s a small ITX motherboard with the dimension of 6.7” x 6.7” (17.02 cm x 17.02 cm). it has a single CPU socket with 3647LGA, the motherboard support 4channel of memory up to 64GB where any processor with that LGA can support 6 channels of memory but due to small form factor of the size, you can’t get the full advantage (DDR4 2933 memory is supported only when using the Intel® Cascade Lake CPU and Intel® Cascade Lake BIOS).

It has one PCI slot for a graphics card, 2x1Gigabyt RJ45 via Intel® integrated MAC X722 + Marvell Alaska 88E1514 Ethernet port, one VGA port and 2 USB 3.1 2nd gen port. For more additional port see below and check the link.
