[mg83790] how draw box with open front

[Murray Eisenberg <murray at math.umass.edu>]

In Mathematica 6, what's the best way to draw a convincing box 
(rectangular parallelepiped) with an open front?

Of course I tried Cuboid, but no matter how I try to treat the faces, it 
still looks like the front is solid, too.
