They are good computers, but they're so overpriced. You can build their computers, with the same parts, for less than half their prices, if you do it yourself.
Those brands that make computer are for people that want a "great" computer for gaming or whatever the reason but don't know how to build one themselves but have the money to buy it.
But is like b1gapl said they are way overpriced.
Do you really think you can't get your own cool looking case? Yes you build your own becuase it's so much cheaper than places like Ibuypower and Alienware.
