If you are modifying your computer case for venting. This works perfect for it. My computer case had a solid front panel which was restricting the air flow. I removed the solid metal front center piece of sheet metal and replace it with the egg crate louver. It lowered the temperature in my case by 20 degrees. Which in turn allows all the major components CPU, GPU, Memory, storage to run cooler. This product is very well made. Nice and glossy black, thin and strong. I'm sure it's perfect for its intended use also. The shipping was extremely fast, I ordered it on a weekend and had it within 2 days. Carefully packaged to assure no breakage. And a perfect transaction to top it all off. PS. I am on a lot of computer modifying web sites and since I've used this, I have been sharing the link to this product so others can do the same modification to their computer cases.
