I did that once. I just drilled a hole at the bottom, ran the wires, and made an aluminum case out of sheet aluminum from Home Depot so I could still store my paperwork and what not. Awesome concept, but not very practical. Every time I wanted to change the CD, Station, or just turn up the volume, I had to reach over and open it if I was alone. Also, if my windows were open on my passenger side, everything would fly out of the glove box. It was frustrating.
