Thanks Bodia.
Most PRS guitars including the SEs will fit the PRS case, but I had trouble with my 2012 SE Tremonti Custom, and the ZM.
They would not lay flat.
I now own four of the SKB cases, but they are not cheap, around $250 each.
But to me they are worth it as the guitars lay flat, and you can tow the case like luggage since it has wheels on one end.

Here is my new S2 I got last Thursday in a new one.
This case fits about any PRS guitar.
