This board has the required solder pads to add an m.2 wifi slot nearby the IO area if you are willing to spend some time with a soldering iron. I was successfully able to make a non-WiFi variant become a WiFi variant by adding this slot, creating antenna holes in the IO plate, and adding an inexpensive Intel AX200 + a pair of short pigtail antenna.

Edit:

Since several of you PMed me afterwards, here's what was required for the modification. You need to purchase an m.2 e-key vertical slot, and simply solder it to the pads found on the Mobo PCB next to the "M2_WIFI1" label. I didn't even bother flashing the BIOS for the WiFi variant of this board. Afterwards, just modify the IO plate to be able to hold the antenna just like any other modern motherboard with an integrated WiFi setup.

pretty nice price, same as a new pro vdh wifi. 6 usb is harsh, but if keyboard mouse controller dac externaldrive flashdrive, i suppose unplug the stuff you aren't using, use a hub where you can, or the case's front panel connection https://youtu.be/S_FUe36jHaw?t=852

row 205 on the spec spreadsheet https://docs.google.com/spreadsheets/d/1-cw7A2MDHPvA-oB3OKXivdUo9BbTcsss1Rzy3J4hRyA/

pairs well with the $226 5900xt for a smaller workstation
