What kind of case does this notebook have?

I would like to grow a laptop in the near future and have already found a suitable one… It is important to me that this is not made of plastic.

Does anyone know if it is made of plastic or aluminum (from the outside)?

There are no Schleppi's only made of aluminum. Plastic always has it. Is not different.
