Don't go PC Specialist - build quality is non existent (mine is not even 2 years old and falling apart already), driver support is poor and performance is much under what you'd expect from the spec.

Also support is pooooooor - been trying for months to get a new LVDS cable for my screen. I keep getting so far in the process (via email) and they say "ok I'll check when we can get one out to you", hear nothing for a few weeks, email again and get a "if you give us a call we'll talk you through reseating the cable". Can't face phoning them yet, but my screen is getting more and more fussy about what angles it'll work at so I'm going to have to suck it up and deal with tech support :((
