    Hi all,

    I´m redoing my front panel and the last time I´ve respected all the grounds but..

    Can all those grounds be tied together in a single cable without problems?

    Image borrowed from the internets to clarify what I´m talking about if there´s any remaining doubth:

    IDE LED is not going to be used and I´m going to ad a buzzer for that scary beeping moments.

    Thanks in advide.

    For the switches and the speaker, yes, you can. You must make sure that you get the connections right when connecting to the motherboard though.

    It is not recommended for the LEDs -ve joints because the motherboard may not necessarily drive the LEDs from the cathode. They might be connected as common cathode and have their anodes 'floating' through an open collector.
    Also, some motherboards have dual purpose power led drives allowing for both power and sleep modes to be reflected by flipping the polarity of the power led.
