Which case is better?

Kinda like asking "What's the best tool ?" Hard to answer unless I know whethwr ya wanna bang in a nail, take out a screw or torque down a valve cover :).

What ya gonna put in it ? Single GFX card, tri SLI ? overclocking ?

If it's single GFX build with moderate OC'ing, I'd recommend one not listed:

Antec 300 - $59

Antec 300 Illusion - $69

If ya thinking double GFX, for $10 more than 2 of your posted cases, you could get the HAF-922
 
I dont live in the US, well the stores here dun really sell antec cases,mostly coolermaster and NZXT. The price of this 3 cases are almost the same here. I'll most likely use a case for OCing with a V6GT. As for looks, the scout looks nice with the handle but doesnt really look like i'll use it.
 
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...
 


Well yeah i was planning the V6GT with intel i5-2500k.

The Hyper 212+ cost 44 USD here instead of 25 on amazon which i find just overpriced.
While the V6-gt cost 69 USD here,59 on amazon. But still cutting out the shipping. The V6 seems more cheap.
