Need help building my rig

[tab]

I just need a bit of help with the computer building process. I'm not completely sure where to put some things on the motherboard. I don't have a manual for the board nor can I find any specific info as to how it should be put together, so I was hoping maybe some of you guys would have some insight.

Here is a picture of the board with general pointers.


Here's a pic of what the computer currently looks like

Here's the hard-drive which I can't find the slot for


And these extra wires on the power block wtf??????¿


This must be a second GPU plug, identical to the one currently plugged into my GPU.

And then there's these. There's two of each kind, with three connectors on one wire like Christmas lights.

This is where someone says to use new parts

Also mind listing out exactly what the parts are that you have? Going off solely from pictures makes it near impossible to do so

The Gigabyte GTX 1060 is my GPU, and the only part I got myself.
The rest were sent to me by an old friend of my mom's who works with computer stuff, so I don't know exactly how old or compatible they are, but I trust his judgement seeing how much he knows about it.

These are:
The motherboard, an ASUS A85-V Pro with an AMD APU/CPU to start me off (I'm going to upgrade it so don't scold me for bottlenecking my GPU)
4 sticks of Corsair RAM, 6GB each
Western Digital 500GB HDD
SolidGear Neutron 550W powerblock
And a CPU heatsink, which I would assume is from Cooler Master judging by the small box of heat-sink supplies with the "COOLER MASTER" brand on it that he also sent

P.S.: I think I just figured out how to install the heatsink. Do you just glue it on there with the stuff in the syringe?

Edit: I read a guide, I understand how to do the heatsink now.

Edit: Heatsink is locked in place.

Edit: Thread locked, I'm all set.
