If you need it for fan grilles, Coolerguys has mesh fan grilles like this. They're the only ones I've seen. I bought a 120mm one for the blowhole project for my new case.
I painted mine from stainless steel to red.
Kinda hard to see in this pic, but you get the idea. There's red behind the motherboard, red to make the PSU cover, and a small black piece on the PSU as well.
