Product Description

Size: Mid Tower | Color: HAF 912

Cooler Master's HAF 912 further enriches the HAF series by adding a compact, yet fully featured, mid-tower solution for enthusiasts and budget conscious gamers alike. Its seemingly small exterior supports a plethora of interior features such as twelve devices, high end GPU cards like the ATI Radeon HD 5970 and the NVIDIA GTX 480, large CPU coolers, two 200mm fans, and six 120mm fans. The HAF 912 embodies the rugged aesthetic and qualities of its brethren while remaining attractively priced. Its traits more closely resemble that of a mid to high-end case than that of other cases in its price range. The HAF 912 pays tribute to the legacy of HAF 932 & HAF 922 in ease of installation, high airflow, and compatibility with water cooling hardware.

Size: Mid TowerColor: HAF 912 Verified Purchase
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.

Size: Lan BoxColor: Elite 120A Verified Purchase
Guiderails are supereasy to add 3.5" harddrive.
No sharp edges.

If you have not build small form factor PC before, make sure that watch youtube videos. You want to add the components in certain order.

For me
- remove the front panel
- remove the cover plate
- remove the bracket for PSU

- mount the DVD Burner first.
- put the front panel back
- mount the 3.5" hard drive

- layout out the cables from the front panel
- mount the CPU onto the motherboard (without the heat sink)
- connect all the power swtich, hard drive, speakers cables from the front panel to the mother board (anything that is hard to read or connect)
- connect one of the fan as system fan onto motherboard
- mount the mother board
- add the memory
- connect the remaining cables, like USB 3.0 and USB 2.0
- connect the internal SATA cables to your drives
- connect the fan from the heat sink onto mother board
- mount the heat sink
- mount the PSU onto the bracket
- partially slide in the PSU unit, connect the power cables to mother board, drives, and fan etc.
- complete slide in the PSU unit into the case (slowly), you don't want to knock out any cables that are already connected
- mount the drive
- tidy up all the cables, make sure they are not blocking/touch any of the fans, in particular the one from the heat sink.
- close the case
- plug it in and power it up

enjoy your new machine

- Wish it came with extra fans and better air filter, other than that I am very happy with the case.

Size: Lan BoxColor: Elite 130
As a previous owner of the Cooler Master Elite 120 and a Fractal Design Node 304, I'm really fond of the mini-ITX form factor. In particular, I'm a big fan of cases that allow you to reduce the footprint of a computer while also permitting the use of high-end hardware and good cable management. The Elite 120 was great for this purpose, with the only problem being that its stylish brushed aluminum front limited the amount of air that could be moved by the included 120 mm fan. The new Elite 130 by Cooler Master fixes every problem from the previous iteration while somehow slightly reducing the case's size and adding in a few more features that computer builders will appreciate.


Upon opening the case, it's impossible not to notice that a lot of thought went into improving things that people didn't like about the Elite 120. The most noticeable change is the inclusion of a sleek black mesh front. The front has seen a redesign with the 2:1 USB 2.0 to 3.0 ratio inverted; the front of the case now sports two USB 3.0 ports. Also new on the front of the case is a much sturdier and more stylish looking power and reset button combination. For those with precise vision, it's also worth noting that several centimeters have been shaved off of the dimensions of the case, though it's worth noting that the slightly-jutting bracket that allows for a full-size ATX PSU remains.

Inside the case, as in the previous version, Cooler Master has done a good job making it easy to get to all of the cables that will find their way onto your motherboard headers. Also bundled is a zip-lock bag with the standard fare that you'd expect for a computer case: motherboard standoffs, zip-ties, and screws.
