Which CPUs fit this board?

It uses the LGA4677 socket and Intel W790 chipset, so it takes Xeon W-2400 and W-3400 series processors. Consumer Core CPUs will not fit.

How much memory can it hold?

Eight DDR5 slots support up to 2 TB in quad channel, with ECC. Rated speeds reach 6800 MHz when overclocked.

Does it have built-in Wi-Fi?

No. Networking is a single AQUANTIA 10Gb Ethernet port, so Wi-Fi needs an add-in card.

How many graphics cards can it run?

There are four PCIe Gen5 x16 slots, so multi-GPU setups are possible. Check your case and PSU for the space and power.

What storage does it support?

It has PCIe Gen5 x4 M.2 slots, SATA ports and U.2 mini SAS. That covers fast NVMe drives and bulk storage.

Is it worth it over a consumer board?

Only if you need Xeon W CPUs, ECC memory and many Gen5 lanes. For gaming or light work, a mainstream board is simpler and cheaper.
