Should I cut the PVC in my Kitchen Drain?

I am replacing my kitchen cabinets. I am not sure how to handle the 2in PCV drain from the sink- ie should I cut the PVC, make a hole in the cabinet and join the pipe or cut a "U" slot in the cabinet and slide it down (ie avoid cuts to the drain pipe). How is it normally done and if I have to cut the PVC and re-join- is it easy?

Answer:
The most usual approach given what you have would be to cut the pipe and install a union, so the pipe can be taken apart and put back together. Obviously the last person chose "cut a big weird hole" as well as doing some very dodgy wiring while they were at it.
You'll need to do the same for the supply pipes.
