When choosing a case it is important to make sure it is something that you like and that will fit your needs. Cases are one of the few, if not the only component from a PC rig that will last you through multiple builds. With that in mind, I took a long time researching and browsing around before I decided on a case for my computer build.

The HAF 912 was consistently mentioned across the web by PC enthusiasts and amateurs as a strong case choice for both form and function. Cooler Master named the HAF series to stand for "High Air Flow" and these cases truly shine in that area. I am running an AMD 955 black edition processor overclocked to 4.0gHz and also a Radeon 6950 1gb video card and the case stays between 27-40 degrees celsius on the stock fans (depending on if I am just browsing the web or utilizing more CPU power). I thought I would need to purchase a bunch of extra case fans in order to keep my system temperatures down, but such is not the case. The huge vent in the top of the case can accommodate up to a 200mm case fan, but for now it works very well as just an exhaust vent. Most of the hot air exits through this area.

The 912 also takes a minimalist approach in terms of design and does not include a giant window or bright LED lights like some other cases boast. For myself this was perfectly fine, but if you are looking for a case that has all of these extra features then this is not the right choice for you. I didn't need a flashy case and instead I wanted my money to be spent on build quality and necessary features. Here are some of the key reasons I would recommend this case to a prospective builder:

Airflow- Superb, even with only the stock fans (discussed above).

Capacity/Size- There is plenty of room inside this case.

I am putting together a machine with the MSI Big Bang XPower MoBo with an i7 930 CPU, and will have a GTX 470 GPU, with 7 HDD's in various raid configs and a Corsair HX850 PSU. This case is so well thought out. So far no negatives except it is very big, which is actually good, as long as you understand this before you buy.

Cable mgmt is excellent, USB 3.0 on the front as well as Esata and 1394 and USB 2.0, covered on/off switch (reset too).

Wheels are included. Air filters on all openings - except for some reason not on the bottom in front of the PSU. All tool-less drive bays, 2 hot swap drive bays in front (amazingly these are not tool-less..wtf were they thinking?).

It includes 3, 200 mm fans (top - out, front - in, side - in, and one 120 mm on the rear out. It also has a place for a second (optional) 200 mm fan on the top.

So far it has been a pleasure to work with. I will update this as the build progresses.

update - the only thing marginal are the hot swap drawers. they require screws to hold the drives in (the included thumbscrews work at least) so it not terrible, but it would have been cool to have a method to yank drives in and out with no real effort at all. still 5 stars

What a case! I went from a mid-tower to a full-tower chassis. Cable management was a cinch. Of the 3 hours spent transferring parts from old chassis to the HAF X, maybe 30 minutes, if that, was spent on cable management. I'm still new to building, however, this case made me look like a professional.

Couple of minor issues:

1. There is a red LED 230mm fan located at the front, a 200mm non-LED fan on the side panel, and a 200mm non-LED fan at the top. Cooler Master allows for an additional 200mm fan at the top of the chassis. Since I didn't go with a water cooled system, I decided to install the additional 200mm fan at the top. However, Cooler Master only sells a red or blue LED 200mm fan. With that said, I took the fan from the side panel (non-LED) and placed it on top along with the other pre-installed 200mm fan, and placed the new additional red LED 200mm fan on the side panel. Looks awesome. Another issue though was that the screws that came with the additional fan that I purchased are different from the screws on the pre-installed fan at the top. I had to contact Cooler Master to send me the exact screws they used on the pre-intalled fan.

2. In regards to the USB 3.0 front inputs, you'll either need a motherboard that supports USB 3.0, or a PCI USB 3.0 card to attach the cables to.

Other than that, the case rocks. I also installed the Cooler Master V8 and not only does it look amazing, but got my temperatures down by like 5-10 degrees!

I just recently built a new PC using this case, and I must say, it is hands down the best case I've owned so far. The build quality of this product is superb and offers plenty of room for a fully-loaded PC.

Here are a few things I really like about this case:

* It came with a bay specifically for solid state drives.
* Cable management to tidy up the wires.
* Removable front hard drive cage for more room and better airflow.
* Built for using a bottom-mounted power supply unit.
* Very easy to remove the front slots for optical drives (it even comes pre-built with an easy tool-less open/lock mechanism to hold the drive in place).
* Even though it comes with 2 fans, there are plenty of upgrade options for those who want better airflow (although the 2 fans it came with do an excellent job).
* Huge cut-out for those who install larger after-market CPU coolers.

Overall, I would definitely recommend this product to anyone. It would be hard to find a better case at this price range.
