[sdiy] Extruded aluminum side source for case?

[doug at synthark.com]

Does anyone know of a good source of extruded aluminum sides like these: 
  
https://www.protocase.com/products/electronic-enclosures/extruded-consolet.php

I'm trying to update our cases, but no one wants to just sell me the 
extruded aluminum sides (everyone wants to build the case for me).
