Dont worry about a different cooler if your not overclocking. For $5 more, you get 140 extra gb, why not? And the bigger the hdd, the faster it will be. I only recommended a new case because I personally dont like the looks of it. Dont buy it just because it has 4 fans. More then 2 fans will just add extra noise and dust. Maybe if you were ocing it might be a good idea, but since thats not an issue
