I would NEVER buy any device from iBuypower or CyberPowerPC. I see an extremely high number of problem units, both here on Tom's, around the web and through my daily servicing of units, plus a relatively poor accounting when it comes to customer service from those snake oil salesmen. I would recommend buying from an OEM that has good quality and good customer service like HP, Dell or Lenovo.
Most OEM's have units with options from the most basic, to the highest end hardware available in any machine, plus customer care programs that far exceed what any of the "custom" vendors offer. There are of course a couple of exceptions to that rule. The Sager custom units are usually well built, but since they're sold by third party vendors in most cases, you are again at the mercy of the vendor warranty program and most of these type units don't offer warranties that extend beyond what the seller provides except on a subscription basis which you'll have to pay for additionally. In other words, once the warranty from the vendor is over, don't bother contacting Sager about it unless you have a subscription based support contract.
What are your priorities for this laptop, from most to least important, and what country are you in?
