Which pins on t3600 must be connected to new standard case's front panel ?

[Fedora7]

I have the t3600 motherboard but don't have the t3600 case. I plan to use a new standard case for it. Which pins are mandatory to be connected to avoid boot error/alert ? I know I can connect the Power on, HDD LED, ground from motherboard to the new front panel in the new case. But I don't know how to deal with the "in sense" and "cent out" pin in the chart at https://github.com/Thorfusion/oemhacks/tree/main/dell/precision/t3600 . Thank for providing the information to make the board live again.
