I have a couple of wooden enclosures, they're quite common in the hobby. I used sliding tempered glass doors, though, no wire mesh anywhere on it. I had sliding plexiglass doors in my first homemade enclosure, but within 3-4 years the doors had gotten so scratched up and foggy you could hardly see through them, and they starting bowing in the middle to the point they were difficult to open and close.

If you were planning to buy one and modify it, it depends on how large it is and the shape on whether or not it would be appropriate. I would completely get rid of the mesh and replace it with something else, but it might just be less effort to make your own from scratch, depending on how handy you are.
