Look up Parker cases. I have one which I used for both my 11x14s (Phillips Compact and an Explorer). They are excellent, wheeled and suitable for checking if you want to fly. I have one which carried my 11x14 and three holders and was only 62 linear inches (compact enough to check without an excess baggage charge). I've taken an 11x14 around the world in one - they are great cases (a Ron WIsner find I believe). If someone is interested, shoot me an email - I have sold my 11x14 so I don't need the case!...
