Rust themed case mod?

[zombieshy_guy81]

So I've been wanting to do a game themed case mod for a while now but I just really haven't found a game that I've liked enough to commit to a case mod for but recently I've really fallen in love with rust and i want to pull the trigger on a case mod but I've been having a really hard time thinking of any mods that would make sense and/or wouldn't look super tacky. So basically I just need some ideas, the case in working with is the cooler master H500P, now I'm open to cutting the case up a little (really just the front and top plastic pannels) and I do have access to a 3D Printer so I can print mods. Just spitball some ideas for me in the comments. Any feedback is appreciated!

A rusty paint job on the mesh would be cool but would prolly be hard and would end up chocking airflow. Do a cool paintjob.
