S & S Coupled Bikes - How hard to pack?

Do any of you have experience with S & S coupled bikes. I bought a never built up 2003 19" terry isis frame on ebay for a song, and am thinking to have S & S couplers installed so I can build it up as a travel bike (my beloved bike friday PRP was stolen more than a year ago). Do any of you know how much I will have to disassemble it to pack it? I have heard that sometimes you have to remove the fork, crank arms and rear derailleur, but is that just for large sized frames? I was planning to buy the standard S & S hardshell case for it.
