A UK-based computer component site?

Thanks to the suggestions made in this thread, i’m considering building my own PC. Can anyone recommend to me a decent site based over here that I can buy components from?

I got a pretty good price on laptop memory from offtek.co.uk, but I can’t speak for anything else on the site (it’s memory only, by the way). The delivery is fast and the packaging is good.

Places I’ve bought stuff from without a problem:

Or, as you’re in London, take a walk down Tottenham Court Road. Or just go to a Maplin store.

Oh, one more: http://www.overclockers.co.uk/

I like Maplin, but their computer components tend to be a tad expensive IMO. I’ve bought from Dabs, and also http://www.microdirect.co.uk/ .
