Yeah - one graphics card doesn't cut it when CrossFire and SLI are in the article name.
I've got a HAF-X with 2x RadeonHD 6990 cards in CrossFire... and can confirm that you missed seeing all the flaws because you didn't review it properly.
1. The bracket doesn't cover the 6990s - it physically cannot be made to fit.
2. The fan sitting behind the graphics cards also does not fit with 6990s - they take up more room than the cards allow. Even if they did fit, it would never work with 4 graphics cards (if you were going that way) - it's only designed for 3!
3. My HAF-X case didn't come with the USB3 header cable. When I contacted CoolerMaster about this and asked them to send me one, they basically said "Yeah we announced we would send them out to people who missed out, but we only meant it if you're in the USA and you're not so..."
Further, the case cannot handle the heat. The top fan of the HAF-X above the CPU actually warped out of shape and started making a huge noise - the blades started hitting the metal insides of the case. I had to move the fan to the opposite side of the frame - hanging from the metal roof, instead of sitting on top of it.
And the alignment of the PCI slots is off. I originally intended to go 4-way SLI with my HAF-X (before going down the CrossFire path), and realised it would not be possible (using my Gigabyte GA-X58A-UD9 at least). The top two PCI slot ports on the case do not match up with the top two slots on my motherboard! The third & forth case slot would be for graphics card 1, 5 & 6 would be for card 2, 7 & 8 would be for graphics card 3... but if I wanted a forth card, there is only one slot left!
Now, CoolerMaster did cut a hole internally so you could plug a card that overhangs unto the missing 10th slot... but one problem - since there is actually no 10th slot where the heck would all the hot-air go? Yep - straight back into the card. You would be mad to try it on air - otherwise the card would get GPU death.
Needless to say, deeply deeply disappointed with the HAF-X due to wanting a 4-card setup, which the case clearly isn't designed for. Your article missed every one of these flaws!
