Sorry ... a bit off topic.
Check http://www.resellerratings.com/ to reduce risk when buying a

I had the same concerns so I bought an Alienware laptop. 2 weeks
after this screaming fast beautiful system was up and running the
hard drive system failed. My 3 year on site support contract meant
nothing. 3 weeks of calls 3 times a day and no cable to repair the
problem. The cable was not the problem. I finally had to do a
chargeback with the credit card company to get a refund. I will not
recommend them for a system you need to do serious work on.
