Hi Thanev,
The case neatly holds in its dedicated cutouts the MM, the charging hub (with the two spare batteries inserted in it), the remote controller, and one of the small cardboard boxes with the spare props. (I put the two unused controller cables and the two charging cables in this box as well, and put the box below the charging hub in the case's cutout).
I can also put the quick charger in the box next to the MM and the case closes easily without pressing on anything, so you don't need any aftermarket case in my opinion (Unless you want one which would also hold the propeller guards - but you wrote that you don't intend to use those).
I hope this helps.
Happy flying!
Las
