Takealot has some z390 boards.
Edit: nevermind missed the "itx" part
I think you're seeing the combination of 10th gen around the corner and the effects of human malware on the supply chain
There should be one ITX board launching soon with the B550 range.Is it just me, or are they impossible to find these days?
I've looked on all of the computer websites that I know about, and I can't find anything.
