Wow, now thats really cool.
But Haf - X has something else offered to gamers compared to Corsair.
In short : HAF X or 932 is good a Air & as well as Liquid cooling, but Corsair 800 is always good with Liquid & HAF X is just little bit smaller than Corsair 800D. Whereas the headroom & built of Corsair is of top notch as well as Price, but HAF is a beast.
BTW let not forget this "
A BEAST DOESN'T LOOK GOOD, BUT PERFORMS LIKE A BEAST". This is the case with HAF.
@S_V: Whatever accessories are included in the link posted by you are already included with HAF X Cabinet, instead of buying it separate..
Case Accessories - Cases
1. Graphite Series™ 600T Side Panel with Windowed and Mesh Inserts
2. Hot-swap drive tray for Obsidian Series® 800D.
3. Obsidian Series® 800D SATA 6Gb/s Upgrade Kit [These are common in new mobo's itself]
4. Obsidian Series® 800D/700D Front Panel USB 3.0 Upgrade Kit.
5. Windowed Side Panel for Obsidian Series® 800D/700D Full-Tower Case.
Corsair launched their cabby's as not only Best and world Class . They also designed to get updates and available for low cost for their Front and Hot swap with latest updates such USB 3.0 and Sata 6 Hotswap which is very sweet and rare thing to happen in Cabinet Industry. I am really Happy that my cabby is update to date for all Features available out there..
All the above things are listed are already available with HAF, may be the quality of the build may vary but don't go wrong with a HAF buddy.
