It's not worth the 3 weeks of headaches and late nights.

The relatively tight packaging constraints one has to work with in FRC robots make designing after your spec is understood an imperative.

Like some of the previous posters mentioned, you want to make sure that you have easy visual access to the status LEDs. We didn't have any issues with passing inspection. In fact, most of the inspectors appreciated the effort the team made to make the wiring as clean as possible. I recommend building a prototype of the box in the off-season. We built a prototype last summer, learned a ton, and then redesigned the box we used in the 2015 season from scratch using everything that we learned. Here are the CAD files that we used for 2015 box, the prototype, and our 2015 bot (so you can see how it attached to the robot).

It's a lot of work, but the effort pays off. In roughly 40 matches, our 2015 bot had zero electrical issues. |
Congratulations on the significant improvement in reliability! Please be clear though. This increase in reliability was more likely due to greater thought and care being given to the layout and construction than the fact that your control system was enclosed in a box. Since putting in place a better construction standard that includes verifying the quality of all connections (crimps) we have had only one electrical failure in the last two years. That failure was a loose crimp in an old battery cable.
