Few things, I upgraded the storage to include a SSD, which is a must these days. Alienware wanted +$250
I upgraded the video card to a better one, a Nvidia 760GTX. They did not have this option. But its about $100 more than a 660GTX that was the standard on the $1400 build.
Also I downgraded the i7 to a i5 since the i7 has no benefit in a gaming system.
They also did not mention an after market cooler, but I included one so your system does not sound like a jet engine. Also with that cooler you can then overclock the processor like they have theirs overclocked, even more. a typical light overclock is around 4.2ghz, they have theirs on 4.1ghz.
The motherboard you can also scrimp on, and get the Extreme3, the one I linked has an option for dual or triple video cards. Not sure if you are into that sort of thing.
The case, I just picked a generic antec. Obviously the case is a choice only you can make.
So to finish, price wise I will call the processor downgrade and the video card upgrade a wash, $100. The SSD, Alienware wanted $250 for probably a generic POS one, Youre getting a top of the line one.
So Alienware price with SSD$1650
Your price for building yourself$1250
If you want to spend the full $1400, I would recommend getting an even better video card, Maybe the 770GTX?
