So the Universal IO Mesh isn't that bad. What cutting tool do you have at home? How well you cut holes is up to you. If you have a motherboard behind it, the I/O shield should "hold up" fairly securely. That's why I deducted a star. But if you have nothing beyond the generic I/O grid. , it can spring open at the slightest pressure. I needed an I/O shield in a case for a non-traditional PC motherboard project and needed to use Sugru modular adhesive to hold the I/O shield in place. something to consider. It's also plastic, so take that into account if you're doing something that requires a metal plate for any reason (grounding or electromagnetic shielding considerations).
