x=pin, o=no pin, connected in bold and colored.
violet: power on led, I think the colored lead on the left-most pin of that set
orange: reset switch
blue: harddisk led, not sure where the colored lead has to go
red: power on switch
for the switches and the speaker, the polarity doesn't matter. For the LEDs, they won't turn on when connected wrongly but it won't damage anything if you do connect them wrong at first. Let me know if and how things work out and where the colored (+) leads of the LEDs need to go.
sorry they're not better, I keep missing the (rare) sunshine!
You have to be kidding me, these are far more than adequate for this purpose
