If the consolization was done right, they are still usable in a cabinet, but it's impossible to say for sure since all consolizers have a different process. If you could post some pics, we could tell you for sure.
But like Ely said, there's really no point in getting a consolized unit if you're just going to plug it into your cab. A lot of work goes into a nice consolized board, and you're most likely going to be charged a pretty penny for that work. If you're just going to plug it into a cab, just buy yourself a regular MVS board.
