Pros: A collector's Item and Great Case that has the room to fit just about any component configuration or water loop you can throw at it.
Cons: The Cut-out on the motherboard tray was too small, the two Hot-swap Drive bays on the front can be unreliable over time.
I currently own this case,(Look at the "NVidia Green" rig in my sig for pictures) and I couldn't be more happy with it. It might not be*THE* Best case you can buy, but in my opinion, it's definitely one of the best, and I will explain why I believe this.
The NVidia Edition is *nearly* Identical, in structural design, to it's Standard HAF-X cousin, with the green Colored Top, front, panels, Drive trays, green tinted half-window, and NVidia Branding on the Right side panel and front intake fan mesh, being the exceptions.
The Case comes stock with 2x200mm fans, one installed on the top for exhaust, and one installed on the windowed left panel, as well as the big 230mm intake fan in the front.
There are also optional fan placements on the top(200mm) and rear(140mm) for Exhaust, as well as two spots inside(120mm, 80mm).
The motherboard tray is non removable and has mounting holes for E-ATX sizes on down. But as stated in the cons, the mobo hole on the tray should have been cut out bigger to accommodate any back-plate for the CPU cooling solution, this was a mistake, but it is not a fatal mistake, and can be worked around often times without cutting it out further.
There are also two hot-swappable drive bays in the front of this case, and some people use them without any trouble at all, but I was not one of those people, so I personally do not use them because I have had a few problems with these staying perfectly tight at all times, and as we all know, the SATA and MOLEX connection with your hard drive is one of those that need to be perfectly tight and secure or you will have problems, to say the least:)
But like I say, some people use them just fine without any problems.
This case has the room to fit some of the biggest GPU's made today(13.5 in)
Here is the Newegg listing for the HAF-X, just look at the 1,300 five-egg reviews/ratings when you land on the site: http://www.newegg.com/Product/Product.aspx?Item=N82E16811119225&cm_re=haf_x-_-11-119-225-_-Product

This case is a Great collector's Item, (discontinued years ago) and sought after my many, (who like this shade of green and are NVidia fans) and is only found priced well over the original $200 - $230 price tag when it first came out.
In Conclusion, If you are a person who is looking for a bigger case that is fun to mod, is Green and black, (talking to those Gigabyte green pre-Z97 Sniper board guys and gals out there)and can hold almost any part you could think of, then this is the case for you!
If you made it down to this far, I thank you for reading this, and remember to do something positive for someone else today if you haven't already done so, even if it's just a "hello", "please", or a "Thank You", it makes a difference!
Have a great day!
