You might want to consider velco-ing the lexan electrical board on like my team did last year. It allows you to quickly remove it (after unplugging the batt. and CIMS) to be able to fix any problems. This works especially well if you have a 2-tiered system, with motors and gearboxes below and electrical up top.

I heard of a team that made a lexan box for their electrical system. After a couple seconds of unplugging, you pull the box out all the electrical is right there. It's much harder to do, and I wouldn't suggest it for a rookie team, but it's a good idea to develop down the road.
