Having trouble connecting the power switch etc cables to a motherboard

I have this motherboard and I have no booklet on it nor do I know which motherboard it is. I don't know the brand, etc. I tried looking on it but it seems to be generic or something since it doesn't say any major brand or model. It has numbers on other stuff like chipset stuff and the on the stuff where you put cables. The little metal pins have no colors nor are they marked with text that allows me to know where to place these thin cables.

If I can get to figure out which motherboard it is, then I could probably find pdf documentation and figure it out on my own but I guess that that will not be possible so can someone help me achieve this?

Any help would be GREATLY appreciated!
Thanks in advance!
