I'm not a big fan off those Prime boards, I've had to deal with memory compatibility and lower than expected overclock headroom way to many times from both the B350 and B450 models. You can find a MSI B450M Gaming Plus, Gigabyte B450 Aorus M or even a Asrock B450M PRO4 cheaper than a used Prime and they are generally better boards.
 
You may not be a fan of them but Asus are better built than either MSI or Gigabyte. As for it being used, same "buyer beware" applies as for anything else, make sure you can return it for refund i it's not good in any way.
Make sure you flash newest BIOS (just came out) and there should be no problems with any RAM up to 3200MHz.
