I see they forgot the IO Shield. A common mistake, both for beginners and experts.
My last couple of mobos have had them built-in, which I love so much it makes me wonder why they didn't start doing it sooner.
Back in the day there was no backplane and the only port on the mobo was the AT keyboard port so that was the only hole in the case. The rest were punchouts for parallel and various serial ports that would be connected to the mobo via ribbon cable. When the first ATX mobos came out they kept the punchouts for the backplane but that required all the manufacturers to use the same port layout so that lasted all of like 2 years before the pop-in shield became the norm.
How are the new ones getting around the different port layouts?
The shield is built into the mobo, not the case. Same footprint as the ones you insert into the case ~~(before the mobo, but dont accidentally bend the spacer tabs and lose access to the Ethernet port)~~ but without the ADHD getting in the way.
Speaking of ADHD getting in the way, despite the previous commenter saying mobo I was still imagining it the other wh around. That makes way more sense.
(Ugh, the number of times I’ve cut myself trying to get the Ethernet shield out of the way)
What exactly does the shield do?
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...
stops airflow
Ah yes managing airflow is a huge priority with this build.
i thought that was the entire point
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.
Keeps the I's O.
I thought it shielded the I's and O's to keep them separate.
