I am going to put some storage cabinets/drawers for tools underneath joists of my raised deck. The deck has a rain diversion system (Trex Rainescape) so there wont be much rain on it. That said I plan to build it out of 1/2 or 3/8 MDO (rated for exterior) like this:

and primer/paint/seal it. (But looking for alternative recommendations)
I was planning on just making using a pocket jig and SS screws. However I worry I will need to get behind the cabinets and to work on gutter or something else, so I was wondering if I should create something I can take apart? If I did, I could fasten the sides permanently and use shelf supports to hold the shelves (and tracks for the drawers). Though I'm still not sure how to fasten the back where I can easly remove it.
Is this at all a good idea, or should I just say, "if something crazy happens just take out the screws and take it apart"?
