Alienware subpar quality

I am very disappointed in the quality of Alienware desktop computers. It's fairly obvious that their motherboards, cooling system human graphics cards are all lower specs compared to computer parts you can buy yourself. On top of that the prices are about double but you can expect to pay on the market to build a computer yourself. I have a Alienware r13 with no instructions anywhere online how to clean it even the guy that took it apart he broke one of the hinges. For a company that makes over $100 billion a year don't nearly offer the service level to match the prices that you charge. You are obviously not trying to be apple because you can never match their level of service but not even 50%. Alienware who once stood for high quality but today it just stands for LED color lights that every manufacturer offers often give me a better quality for a lesser price. I'm very dissatisfied and I want to hear from other people that have had their family were desktop plastic hinges break.
