Review on 🖥️ IOmesh Black Universal IO Shield Plate: Create Custom IO Shield for Any PC Motherboard, Perfect Replacement for Lost Backplate by Mark Loebis

This might work for you in a pinch. Please note that as the description says they are made of plastic. You are a little thin. They didn't really work for my use case. Instead, I designed a custom part and 3D printed it. It's nice that it comes with two, just in case you get it wrong or want to use it with two different motherboards. Please note that the images are mostly 3D renderings. If you want it to look this clean in a case, you have to be very careful and methodical with your cutting technique. I would rather give a slightly higher rating but it's expensive for what it is. At this price it should be metal.
