Short, practical summary for : the usual power and HDD lights and the power/reset switches are wired to the motherboard’s front-panel header (F_PANEL / JFP1). Those LEDs are polarity‑sensitive and the motherboard manual is the authoritative pin map to follow. (corsair.com)

What to check first (quick workflow): open the front bezel, find the little PCB/harness behind the display and look for printed labels on each cable (CD, LAN, HDD, PWR, etc.). If labels are missing, photograph the connectors, then connect the obvious ones first: PWR LED / PWR SW / HDD LED to the motherboard header per the manual. That confirms the board side and clears the basic pins before you try the special icons. (corsair.com)

CD icon: many cases expect a CD‑LED lead that plugs either into a motherboard front‑panel CD pin or directly to the optical drive’s small two‑pin LED/contact on the drive. If the drive has no separate header you’ll often find LED contacts on the drive PCB behind its bezel (or the motherboard may provide a CD‑LED line). Check your drive and the board for a pin labeled CD‑LED before guessing. (manualzilla.com)

NIC icon: this is the tricky one. Some server/workstation boards expose LAN‑activity pins on a front panel connector (or the board offers dedicated LAN LED headers); consumer boards frequently do not. If your motherboard or NIC card has a LAN‑activity/header pair you can hook the case lead to those pins; otherwise the NIC icon won’t light unless you add a NIC with an external‑LED header or run a custom wire to the NIC’s bracket LED. (docplayer.net)

Troubleshooting cautions: work power‑off and unplugged, use the motherboard manual, mark polarity on LEDs, test one connector at a time, and use continuity or a multimeter to trace unlabeled leads. If you post clear photos of the front‑panel harness and the drive/NIC area (as suggested), people can map the plugs precisely; was right that the motherboard ultimately dictates the standard front‑panel wiring.

Better tell us what wiring you got there with the display, mate, and we'll see if we can work it out. The manufacturer website doesn't provide any support documentation.

A bit more info about what wires are there would help a lot!

isn't it the motherboard that dictates where the case front panel wires go!
