Right as its now horribly obvious your knowledge of building PC's is limited at best im saying it now, I will sell this to you if you still want it but my part will end the moment I post it. Non of the leads are needed to make the motherboard work, neither is the disc. The leads you get with motherboards are accessories that is all. All the stuff off the disc can be directly downloaded from gigabytes website. The motherboard itself is in perfect working condition, and I will provide the paperwork form gigabyte to proove it.
But with a RRP of £150 for this motherboard alone, without the graphics card included im not gonna be pissed around by someone being bothered that a cable or disc might be missing, I could easily stick it on ebay and would probably get more than im selling it for here.
Sorry to sound harsh but thats it, im gonna be ~100 out of pocket just by posting ti onhere rather than ebay, so take it or leave it.
