I think the question is about reusing the box they made or used to house the control electronics last year. Without knowing if it was an unmodified COTS case, or a fabricated component, or whatever else it was, it's kind of hard to tell.

This is a good excuse to read the rules about material use in Section 8 and try to understand them. The flowchart helps. (make sure you have the latest revision of the rules, too)

The main reason I can't answer the question is because I haven't spent enough time studying this part of the rules myself, and would probably give the wrong answer based on what we could do last year...and a lot of things have changed since then
