Where can I have a cheap glass box built with a lock (shop)?

I want to put my PS4 games in it and lock them so that everyone can see my games but not steal them.

My question now is in which shops can I have a glass box built with dimensions (cm) that I specify myself with a lock.

It's called a display case and these things cost a few euro more than you think.

Ask the glazier? These are craft businesses that process glass.

Cheap!

You don't get that cheap. It is made by hand. It's cheap at Aldi or LIDL. You have to take what you get. "I want my box measures 18cm high, 14cm wide and 30cm long." costs you at least 1000 euro.
