http://www.w7forums.com/threads/official-windows-7-sp1-iso-image-downloads.12325/ there are some of official .iso files. I have tested one and it was legit. Remember to choose right version.
 
Install all windows updates, drivers and update bios before other drivers. 

The 7750 does not support CrossFireX.

Like Langdon said, it will be more than fine. 2 feet are pretty good size cables. You only run into problems like this when you pick up a really big case.

It'll be fine.

So.... you wanna play all those games on NOTHING , wow you're such an inovator bro!

HELL YEAH that pc will rock man you realy should buy it oh and could a mod move this thread please 

Well you probably have to link some specs first..

neh i would get a better video card more like a 670 or a 760
edit: and i would get a better psu 

Moved to New Builds and Planning section
 
Looks like a good build overall, I think the Kingston V300 would be a better choice of SSD though, and you should change your power supply to the Seasonic S12II 520.

Have you considered something from the red team then if price is a concern, something like a 7950 or 7970?

for the video card i would realy recoment same some more and buying a better one becus this one will not do a good job for a long time and for the psu i would get anthing with atleast 550w

Keep the stock cooler, you will not overclock so there is no need for any better coolers. Crysis 3 kills the best of pcs so to run that on high then you may have a few problems. A radeon 7950 or a gtx 760 would be better much better. Which ever of the above cards mentioned is cheaper is the one to get.

Crossfire ready.

That looks fine, i would save some money and buy 760.

Better: http://pcpartpicker.com/p/1yhvZ

That looks like a fine build.
 
No there isn't really a benefit to having more power than is optimum (~500W for a single graphics card, 750W for dual) it's just a bad idea to have a cheap power supply in terms of build quality though.  I'm not a big fan of the Corsair CX series personally although it's recommended a lot around here; in my experience they have made coil whining noises and aren't the best built.  It is a step up from the Rosewill though and if you're on a tight budget then that might be the way to go.  I'd trust it to work properly, if nothing else.
 
If you aren't big on overclocking then the stock heatsink will be perfectly adequate, although not the quietest.  Keep in mind you can always add an aftermarket heatsink at a later date if you want.

this is my suggestion for your build
