Hey, I’m a total noob when it comes to pc building. This will be my first build and I want to know if I have to buy it separately. Thanks!
Is and IO shield necessary?
Do I really need an io shield?
Can't Find Compatible I/O Shield
IO shield, have to have it? - PCPartPicker
How should I mount a motherboard with a pre-installed IO shield?
Where can I get an IO shield?
I/O shield:

1) Shield to keep electro-magnetic radiation inside of the case
2) Dust Cover / Air circulation director: The fan in the power supply shall draw air throughout the entire case and not just along the short way from the I/O area to the power supply that's usually right above.
3) Aesthetics: No ugly hole.
It's simply for covering the back of the computer, and for shielding your inputs and outputs from being jarred around and damaged when you're plugging in and unplugging things. Some people on this thread seem confused. Because it has "shield" in the name, people think it's shielding against current or EMF. It has nothing whatsoever to do with current, or EMF interfering with radios or anything else. I use radios, I also have no covers on my computer, side front or back. To add to that, the radio I have right now is inside my computer. It's really only aesthetic, there to look good because as a shield for your inputs and outputs most of them are fairly useless without being actually attached to the board and solid rather than thin and flimsy.
I recently bought an ASUS crosshair VII Hero motherboard for my first gaming pc build. I noticed it didn't come with an io shield (if it did I have no idea where it's located) and was wondering if this particular mobo doesn't come with an io shield? I know the importance of an io shield and don't want to statically discharge my pc. The motherboard was bought brand new of amazon and I'm not sure if I should get it replaced. Any advice is greatly appreciated.
