I see they forgot the IO Shield. A common mistake, both for beginners and experts.
What exactly does the shield do?
stops airflow
Ah yes managing airflow is a huge priority with this build.
i thought that was the entire point
Keeps the I's O.
I thought it shielded the I's and O's to keep them separate.
But what keeps the O's I??
Real answer: it serves two purposes. First it ties the ground shielding from the ports to the grounding plane of the case itself so that static discharge is dissipated there rather than the motherboard. Second it completes the RF shield created by the case, this was way more important in earlier in computing and is also required to comply with that FCC rule about not interfering with other devices that you see printed on the bottom of things still sometimes.
So.. Neither is missing from this case. Ain't no shielding happening on this plastic-coated beast
As long as it’s plastic coated metal it should still be capable of shielding any wavelength larger than the squares. So you would still need to put your WiFi antenna on the outside I think.
You know, that's fair. And I suppose that covers radio, so...
It is the underwear for the PC. The PC's nethers will be left uncovered. Although that might be intentional in this case since some people like the breeze in their nethers.
