hey Mana,
Yes I followed Leeuk's instruction's on were to post and how to make the basket. Then posted the basket in the customers service thread (the link is on the previous page) and within a few hours the customer service chap answered the overclocking question and a few other I had; he give me a reference number and a telephone number. I rang them got through straight away and after giving them the reference number then put me through to the person that gave me the quote and we discussed a few things and that was it. He knocked the delivery charge off because the CPU isn't out for a few weeks and everyone I spoke to was very helpful and nice.
The headset are promotional from the companies so they won't knock anything off. no a big drama.
He said he wouldn't overclock the new cpu because its new. I think they didn't really want the liability of doing it straight away, because it a new model; like maybe it would void the warranty or they just wanted to test it on a few first but I could be wrong.
the overall cost was £1632.84.
