First-time builder, tight-budget, need judgment

[HarcoreMango]

So basically, I need a new computer and thought I might as well build one. I need to know if this build will work or not and maybe some tips on how I can improve it. I have done my research but I thought I might as well take it to the "pros" before I go ahead and actually order the parts.

I plan on buying this week and am on a budget of $800~$900. I have a monitor and other peripherals. I also have my old Windows 7 Installation disc and was wondering if I could use that and just get another activation code? My priorities are gaming first, and internet surfing second. I am a beginner at this so any constructive criticism would be helpful. The build is as follows:

Video Card: EVGA GTX 670http://www.amazon.ca/gp/product/B007Z3HZIA/ref=ox_sc_act_title_5?ie=UTF8&smid=A3DWYIK6Y9EEQB]
CPU: Intel i5 2500k http://www.amazon.ca/gp/product/B004EBUXHQ/ref=ox_sc_act_title_4?ie=UTF8&smid=A3DWYIK6Y9EEQB]
Motherboard: ASUS P8H67-M http://www.amazon.ca/gp/product/B004Q7LGZG/ref=ox_sc_act_title_3?ie=UTF8&smid=A3DWYIK6Y9EEQB]
Hard-drive: Seagate Barracuda 7200 1TB http://www.amazon.ca/gp/product/B005T3GRNW/ref=ox_sc_act_title_2?ie=UTF8&smid=A3DWYIK6Y9EEQB]
Memory: Corsair Vengeance 8GB Kit http://www.amazon.ca/gp/product/B004CRSM4I/ref=ox_sc_act_title_1?ie=UTF8&smid=A3DWYIK6Y9EEQB]
Case: http://www.newegg.ca/Product/Product.aspx?Item=N82E16811119197] Also need some suggestions on the case.
Power Supply: I am not sure on this, but I can either get a 500w or a 550w. I'm not sure if it would be better to invest in something more (which right now, I cannot do) 500w http://www.tigerdirect.ca/applications/SearchTools/item-details.asp?EdpNo=4465483] 550w http://www.amazon.ca/gp/product/B001Q3LWL6/ref=ox_sc_act_title_1?ie=UTF8&smid=A3DWYIK6Y9EEQB] If you guys know any other quality Power Supplies that would be better for the price range ($40-$60) be sure to inform me.

There's no point in getting the i5 2500k if you're not going to overclock. Get a cheaper i5, that will save you some money.

Don't get the first power supply, it's Cooler Master, and they don't make very high quality power supplies. Go for this: http://www.ncix.com/products/?sku=59615&vpn=P1550SXXB9&manufacture=XFX&promoid=1016

It's Seasonic manufactured, and Seasonic makes the best power supplies.

Cases are mostly personal preference, just try and make sure your case has good airflow, as in ventilation, and a bottom mounted power supply, with a filter for the bottom mounted power supply.

Good build, Curious as to why your going with Sandy instead of Ivy bridge? Also you'll want to add an aftermarket cooler since your going to be using a K series chip.

Evo 212 is a great/cheap cooler.

So I should just get the i5 3450? How does this look? http://www.newegg.ca/Product/Product.aspx?Item=N82E16819116506]
