A modern motherboard rear I/O clusters USB, video, networking, and audio in one panel

A modern motherboard rear I/O clusters USB, video, networking, and audio in one panel particular entry is a bit of a mess — it came through a RamSeeker import under a DDR5 RAM compatibility product, but the question is about motherboard rear I/O, not RAM. A modern motherboard’s rear I/O panel typically clusters together HDMI 2.1, DisplayPort 1.4, a handful of USB 3.2 Gen 2 ports in both Type-A and Type-C, 2.5 Gigabit Ethernet, Wi-Fi 6E antenna connectors, and 7.1-channel audio jacks. The exact mix varies by chipset and vendor, but the general layout is consistent: video on the left, USB and audio on the right, Ethernet somewhere in the middle.
