Where and how much can I buy a case from getac X500 server?

Question

Marketing

You need a case from getac X500 Server or b300. I want to buy a candy wrapper from a getak, and assemble the filling myself, because the prices for the laptops of that company are very high, and the characteristics are so-so, but the case needs to be light and durable. No matter how much I googled some repair services, but there are no spare parts.
