    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.

        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.

      Yeah, it’s like the difference between sitting in a stopped car with all the doors open vs sitting in a moving car with the front driver and rear passenger windows open. The first one might feel cooler on a windy day, if the wind is blowing in the right direction, but the other will have consistent airflow from the outside through the car and back outside.

        I prefer using the opposite windows. I don’t like a breeze directly at my face.

          I keep my sunroof open and the back passenger side window cracked. It is the optimal airflow for the driver’s seat. I couldn’t tell you what the rest of the seats feel like, but those are of no concern to me.
