My heart isn't set on this particular heatsink but it seems to get great reviews.
Now my personal opinion is a factor here of course. I like the Corsair a lot better. It seems a lot less over the top and classy to me. The CoolerMaster looks like a gaming rig. My main criteria for a case was I wanted a full tower so fitting a high end graphics card (or two) in it will not be an issue. Also I wanted good cable management. Both cases look like they could handle water cooling if I decided I wanted to go that route, but I would assume the two cases both have similar air flow right now. The Corsair seems to win in my eyes in most all the categories (well maybe not in airflow, but the cable management on it looks superior) but it is also $90 more. So I am trying to get others oppinions on if its worth the extras $90 or just save some cash and go with the CoolerMaster.
I Would get the HafX but you dont Need to get a full tower unless your ganna be water cooling or need airflow to cool some stuff... I'd get the Haf 912 Plus OR a Case with USB 3.0... Also your RAM is overpriced... Most 8GB RAM should be under $100 right now so you'd be wasting your money on that 8GB RAM... For it timing, it's good but should even pass $110 awhile other 8-9-8-24 at under $100: http://www.newegg.com/Product/Product.aspx?Item=N82E168...
-Wider to support bigger CPU coolers.
-Up to 7 fans
-Not many cable management routing holes
-Power supply cable cover up to conceal wires
-Can support up to quad sli
-Alot of cable management routing holes
-.10 inch thinner but should still fit the cooler
-Up to 7 fans
Actually, im gonna stop right there. I see no need to spend $180-$279 on a case when there are cheaper solutions that come in mid and full size towers. Like the HAF 922...its cheaper by alot and is very spacious and good cable management options as well. Pretty much a full tower but is called a mid tower.
But if you want me to choose between the two I would say the corsair would prob be easiest to build with because of the cable routing options. Still wouldn't pay that price.
Since I like Corsair for their PSUs and RAM, I'd take the case to fit with it as well. Both cases are created equal for my own tastes..
Pay no attention to the Corsair fanboys. They are blinded by the need to pay more for an equal product which you can pay less for. Such as RAM for example. Corsair usually charges $10-$30 more while having higher timings. To a normal PC enthusiast this is ridiculous but to a Corsair follower its an obligation to pay more for a badge and a name.
By whatever you like. Its your PC, not ours. Silverstone and Antec make some sweet cases!
