Depends where you are in the UK, I had mine built locally at a place called Computer World [Colwyn Bay], they built it to my spec, very similar to yours! Their labour warranty is lifetime on their built systems. They have a web site but their warranty is RTB, not a problem for me but might be for you!

Quad core Q6600, 8 Gig RAM, 8600GT graphics, 2 x 250 Gig HD's in Raid 1 array.
