Useful, thanks for share. Looking the pics imho the bezel is ever the same, but the cases or the CGs changes a bit... J and K-series shoulders are less rounded than M, N and O-series.
Look the gap between the top side of the CG and the top edge of the middle case. Maybe to build a J and K-series, a Noob V3 is correct and to build a M, N and O-series the Noob 390/V4 is your caseset.
