Could this be also made from other material other than aluminium?

I dunno...I like the metal enclosure. One nice thing about them is that they provide some shielding to keep other sorts of electronic crud from getting into the modular from the backside (where there's plenty of unshielded wires, interference-susceptible bits, etc). Just add a ground wire to the cab(s) and run that to your studio's main star-grounding point.
