"Another Slot A motherboard :(, maybe the 4th one I buy from AliExpress will finally be that X870 motherboard I want!"

I've never received something other than what I've ordered. At worst the documentation is scant or missing entirely. Specifically with respect to motherboards, most of the aliexpress specials I've interacted with have had completely unlocked BIOSes. Which are easy to get yourself into trouble with, but kind of nice to have when you need them.
