I have this motherboard but I'm not sure where I'm meant to put in the front panel connectors, the ones I have are:
H.D.D +/-
Reset Sw
Power Sw
Power LED +
Power LED -

The issue is I don't really know where on the motherboard these would go, hoping someone would help me out here.
 
You have a normal complement of front panel connectors.
On the motherboard, there will be a place to make the connections.
It will look like this:

Orient the panel by looking at the open places.
Do not worry if you get the connections wrong, no damage will occur.
If the pwr and hdd led lights do not light, switch the + and minus cables.
You can get amusing results if you connect the led + to the restart pins as I did once.
