Use the measurements below to check for the correct size. These bags (flat) are much closer to 11" x 15" than 12" x 16" as listed. The ATX board will most likely NOT fit, I know the ones I've tried don't fit. So check how much you need and don't forget to factor in the waste of lifting parts on the board(s). I expected them to be cozy which is what I wanted but they are too small. Otherwise they appear to be serviceable bags.
