In regards to your question about the case, it is about an inch longer than my Cooler Master HAF 922, and that radiator will not fit in my case.
I suggest you go somewhere that has that case, Micro Center, or somewhere else, bring a tape measure with you and measure the inside of the case at the top. Those drive bays may be in the way, and/or the rear fan removed and placed on the outside [if possible] - get a fan grille if you do that.
And, if this is going to be a gaming rig, I agree that Ivy Bridge would do better for you, actually, many benchmarks show Ivy Bridge winning over your choice of CPU.
An Intel Core i5-3570K would be a very good choice if you overclock or not and a motherboard with at least 8 phase CPU [mosfits to share the load to keep them cooler]. When you find a motherboard, sometimes 12 phase or higher will be listed on the box, however, 8 phase seldom is, but is fine for overclocking Ivy Bridge.
If you want to pay more money a Intel Core i7-3770K can be used.
Compare prices at NewEgg to Micro Center, if you have one near you for Ivy Bridge prices: http://www.microcenter.com/search/search_results.phtml?sortby=pricelow&N=4294966995%2B4294930330%2B4294922744
