Change the i7 to the i5 -3570k. you don't need a 7 for gaming. get the K version if you plan on overclocking. if you don't plan on OC'ing, you probably don't need such a big cooling fan. The regular FRIO will be more than enough. but i would OC. maybe not now, but eventually. its fairly simple.
The video card is lacking on this build. i would not get anything less than a 7850 (560 for nvidia). thats minimum for gaming in my mind. once you downgrade the two previous items, you will have headroom in the budget to upgrade the video card.
and change the PSU. first off, 1k W is overkill by double for this machine. second, do not get STANDARD PSU from CP. you need named brands. if you plan on possilby Xfiring your GPU in the future, go with about 750 or 850W, 750 is enough, but you never know what the future will bring and you may need more. I like Corsair. the second one on the list for +30 is perfect for what you need and is a thousand times more reliable than the PSU you selected.
i would get the peripherals like the keyboard and stuff from amazon or newegg. price and compare, i'm sure the $$ are far less.
no OS? Win 7?
i would not rush. it just means less quality control and testing. the shipping foam is a good insurance policy against having to ship the whole thing back. the wiring is not needed as they wire the same way no matter what. plus the case is configured for wires to go a certain way regardless.
Dude thanks so much! Best and most detailed response I've ever gotten on any forum website. Thanks for all the recommendations I'm definitely buying this with confidence now. Also I have a copy of windows so I will just install it myself and thanks once again for the help. On an the mouse and keyboard are alot cheaper on cp.
Thanks!!!!! Looks like I got some changing to do...
