Front Panel Connectors

[budderknuts]

I'm building my first gaming PC soon and I'm wondering if cases usually come with the front panel to motherboard connectors for the USB Port(s) and 3.5mm port(s).

They come with PWR, RST, HDD LED etc. HD Audio, USB. 3.5mm I'm not sure.? HD Audio should cover that I think.
