SUSE preinstalled on laptops?

A couple of days ago I asked about buying SUSE preinstalled on a Sony GRT896 laptop in the UK. I didn't find anywhere to buy it, nor anyone who had installed it themselves, so I'd like to broaden the question. Is there anywhere in the UK that I can buy Linux preinstalled on any manufacturer's laptop? I'm looking for a top-end machine, a known brand, good reliability and good service. I'd prefer SUSE. IBM are strong on Linux, so is there anywhere in the UK I can buy an IBM laptop with Linux, for example? Thanks, Dave
