Had a quick look round the site. The bit that put me off was "overclocked as standard" I know I'm boring, and old, but I just can't see the point, I'm afraid.
Why not select a processor at a speed guaranteed by the manufacturer? If you want a fast one..fine. If you don't need a speedy job, that's ok too
I don't know what the after sales service is like either but I do know that Novatech or Dell or Poweroid will sell you a good computer at a cracking price and they will provide a good back up
I may be quite wrong and I'm not looking for trouble from those that know better but is the whole reason for overclocking not really to be able to crack on that you've got something for nothing? Why bother?
