And then my case...

Ok this is my first time building a computer, I've looked up tons of information read up on a lot of the threads here and most of them have answered my questions, but now I got some more direct question and I need some answers too...

1) Do I need to buy any extra cables or does everything I have already come with the cables? That's what I'm assuming...
2) What kind of tweaking do I need to do in the BIOS? I don't want to overclocked anything Nd rather just leave everything how it is.
3) Does setting "Voltage" and "Ram Timing" mean overclocking the RAM? From what I read, yes.
4) Since my i5 came overclocked already overclocked do I need to tweak any settings in the BIOS
5) My harddrive/disk drive came with no cables, do I need to buy the cables for them?

yea, don't pay for it. The hardest part will be figuring out where all the wires from the case connect to the Mobo...then how much thermal paste to add...then how to hide all the wires...Once you do, it is smooth sailing from there. (once you do it, you will want to build another

Thermal paste!? Uh... What? I didn't read about this anywhere

The CPU will require a drop of thermal paste between the cooler and the CPU. There are many ways to apply it. Check youtube for all the different ways. Some like a pea size dot on the cpu then just put the cooler on...some like to spread it out on the cpu (very thin) then attach the cooler...it's easy, just don't add too much. Just watch a video or two.

If you are just using the stock cooler it will come with a goopy kind of sticky pad thing that acts like the paste would. You can use this in most cases since you aren't overclocking. Though actual thermal paste allows better heat transfer between your CPU and heat sink, which will result in lower running temperatures.

Most enthusiast builders recommend not to use the pad things because their performance is pretty bad compared to paste, but generally it's just fine to keep temperatures reasonable.

Yes, Traciatim is right. It's been so long since I used a stock cooler I forgot they have it applied already.
