Jesus H Christ, this thread is filled with so much misinformation/lack of knowledge that any sensible answer is bound to quickly get dog-piled. People suggesting triple-channel RAM for a dual-channel mobo/CPU? Claiming that Seasonic is not a renowned PSU manufacturer? SSD's are not worth it (they most certainly are)? So much other rubbish I could keep digging through...Escapist is definitely NOT a forum to ask about PC hardware, it's the equivalent of asking for sex/dating tips on Call of Duty forums.
My best and only advice to you is to either ask on an actual PC discussion site like Overclock.net [http://www.overclock.net], or any other place which has a solid PC build community. I personally reside on MMO-Champion Computer forums [http://www.mmo-champion.com/forums/290-Computer].
I'll give you some pointers anyway:
> Case - fine
> GPU - save a few bucks and get the regular PE edition (OC it yourself) or Asus DirectCU as it is by far the quietest card.
> PSU - way overpriced and overkill. Yes Seasonic makes the best PSU's, but platinum efficiency is completely pointless. You want a well-priced 450-550w unit...say, XFX ProSeries 450w, Antec NeoEco 520w or Seasonic M12II 520w...maybe a 600w+ if you plan on greatly beefing-up the GPU later on e.g. Seasonic M12II 620w, Antec NeoEco 620w, Corsair TX650 or Antec EarthWatts 650w.
> RAM - meh. 1.65v seems a bit much for a typical 1600mhz CL9 kit. Why not go for a 1.5v kit from Corsair or Mushkin?
E.g.
Mushkin Blackline 8GB [http://www.newegg.com/Product/Product.aspx?Item=N82E16820226191] - $39.99
Corsair Vengeance LP 8GB [http://www.newegg.com/Product/Product.aspx?Item=N82E16820233186] - $43.99
> Mobo - meh. Recommend an ASRock Z77 Pro3 or Extreme4, best bang for the buck motherboards available at the moment. Or if you're not a fan of ASRock then go with Asus/Gigabyte, they both have offerings (Asus P8Z77 LK/LX and Gigabyte Z77 D*3) in a similar price range.
> CPU - excellent
> Heatsink - I highly recommend an aftermarket heatsink, it will run VASTLY cooler than the stock heatsink, quieter, provide OC headroom, look a lot nicer, etc. The benefits are awesome in the long run, you won't regret it. This is the best bang for the price at the moment:
Xigmatek Gaia [http://www.newegg.com/Product/Product.aspx?Item=N82E16835233082] - $19.99
Surely you can spare 20 bucks right?
> SSD - your SSD link is linking to an i5 3570K. But I'll recommend a few anyway:
Samsung 830 Series 128gb [http://www.newegg.com/Product/Product.aspx?Item=N82E16820147163]
Crucial M4 128gb [http://www.newegg.com/Product/Product.aspx?Item=N82E16820148442]
Intel 330 Series 120gb [http://www.newegg.com/Product/Product.aspx?Item=N82E16820167121]
> HDD - where you gonna store all your data?
Samsung Spinpoint F3 1TB [http://www.newegg.com/Product/Product.aspx?Item=N82E16822152185] - $84.99
