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.
