There is a version of the PG Riptide board with a vertical M.2 E-key slot for wifi (under the IO shield). Unfortunately the availability of the wifi version is quite poor.
Would it be feasible to add the m.2 slot to the non-wifi version. Looks like the non-wifi version lacks the metal holder and probably also the board socket. I was thinking it might be possible to solder a compatible E-key header on the board and buy a suitable holder/bracket.
Haven’t found a good picture of the location of the wifi card though, as it’s behind the IO shield. Probably an idiotic idea though.
Edit: went for the MSI B650m-A WiFi instead. First PCIe slot is a bit lower than the others, giving more space between gpu and cpu/psu. Additionally it comes with USB 3.2 gen2 front I/O, whereas the Asrock has gen 1 only
The only case I can see where you’d maybe want to consider doing this is if you have an ITX board, which typically doesn’t have extra PCIe slots (and usually comes with WiFi built in). But I agree that if you have an open PCIe slot, just make use of that.
