I do agree with CheffoJeffo that rebuilding it will take some carpentry skills, but unless you're dealing with a cab that has a bunch of compound angles it's not that hard to cut some replacement panels and put it back together.
Actually, I was thinking of having good carpentry skills for disassembly (e.g. disassembly without having to write panels off).
My big concern is that it doesn't sound as if either of those asking the question have any expertise with either carpentry or cabinets ... it could be an expensive lesson.
ArcadeNoob: Have you looked at the difference in price for shipping ? I am guessing it won't be as big as you think (with the right choice in cabinet shipping). If you are looking for an empty cab, where are you ? Maybe someone here can point you in a cheaper direction.
USSEnterprise: Getting cabs to the basement seems to be the biggest problem for many people (even more difficult than the restoration/acquisition). While I did recommend cutting pieces out of the wall (honest, saw it done recently), perhaps I should have asked what the dimensions of your staircase to the basement are.
And, for good measure, I don't think that TG is actually disagreeing with the majority ... if you are willing to write off (and then recreate) a couple of panels, then self-disassembly can work for you.
Cheers.
