Unlike standard retail mobos, such as the ASUS M4A785-M,
That M2N78-LA, designed and manufactured for HP, has proprietory connectors from the chassis to the mobo...
So there is no "system panel connector" on the M4A785-M.
I got the cables from "micro center" it comes with HDD LED,RESET SW,POWER LED,SLEEP LED,POWER SW.Now ,I have (as u know) a hp m8530f and it comes with 2 lights an one switch(should be power led ?).Could u tell me which ones to use?And since the bottom light is smaller than these I bought which ever goes there can I cut the wires and switch the lights?And God help u to understand what I just said.thank u
