Bought my motherboard used (Gigabyte b450 gaming x) and it does in fact have a m.2 slot. Buying used isnt always a great thing but I got this for a really good deal. Had to zip tie my cpu cooler and did not get an i/o shield either. Now wanting to add a M.2 SSD to my system only to remember I did not recive the standoff or screw to mount the drive. Not sure if its that important but what is a good alternative SSD mounting.
