mike, I haven't read the full thread, however I will advise one thing - DO NOT USE SCAN
I can not stress it enough, they are crooks. Stick to overclockers.co.uk ebuyer or aria, but do not, for your own sake, use Scan. I have unluckily been at the brunt of there fraud and know others who have had near enough identical experiences. So long as they are taking your money they are happy, as soon as you need a single thing from them, expect nothing but hurdles and the blame to be placed on you.
You said you are in Manchester, why not take a trip to Bowlers?
