Opening up Battery Chargers?

[ryaneogilvie]

I have been working on a new battery charging station for our team. I'm trying to get it as small possible while storing 8 batteries. I had seen 2177's cart and saw that they had opened up their chargers. They mounted the light circuit board of the charger up front and the charging circuit in the back.

I was wondering if anyone thought that it would be dangerous to open up/modify the chargers. It would be advantageous for us to open up the chargers, but I wanted to make sure it would be safe to do so. We are planning to make the charging station out of .09 aluminum sheet metal.
