Will this support ECC memory?

The provided product information does not mention support for ECC memory.

Does this support DDR5 4800?

No, this motherboard supports DDR4 memory, not DDR5.

can it support a ddr3 graphics card?

The product does not mention support for DDR3 graphics cards. It supports PCIe 4.0 and PCIe 3.0 slots.

Where is the Wifi 6 card port? Also, is card included? I see 2 pcie 4.0 ports, but neither look compatible, or the shield is hiding it. Thanks

look at the second pic, and zoom in on the top left... standard laptop M.2 wifi/bt module with some jazz to make it part of the IO panel
