if possible get a better cooler... V6GT is a good cooler but there are much better ones in the market... where r u from??? what cpu do you have??? if its not X6 or i7 9XX series then you dont need more than the hyper 212+ which is as good as the GT for a lot less price... for those high vcore cpu's you need something like prolimatech megahalems or thermalright venomous X or notua NH D14 or thermalright silver arrow or tuniq tower 120 extreme... if these are not available in your country (where is it anyway???) then the V6GT will be a better alternative...
912 advanced is probably the best of the choice if it were up to me... a fat case which can accommodate a lotta stuff with good cabling and excellent cooling... this case will accommodate any cooler size...
