Cooler Master HAF 912 Computer Case Review

One of the great things about a free market are the options. In today's computer market there are options between brands and even within brands. Cooler Master's High Air Flow (HAF) series is one example of products designed to fit a range of different needs. The launch of the HAF 912 helps fill out the offerings from the HAF series of feature rich computer cases. The HAF 912 is a mid-tower offering to satisfy both the fanatic and the frugal. In this article Benchmark Reviews compares model RC-912-KKN1 with the rest of the HAF lineup to see how the 912 compares to it's older brothers. As a budget case it will certainly try to offer as many features as possible, but ultimately it costs less because some sacrifices must be made compared to the top of the line products. Read on to see how the HAF 912 approaches the often precarious balance between performance and cost.

One of the risks of a free market is the choice facing companies on how to design, build and present a line of products. For the HAF series Cooler Master has already released the HAF 932 , HAF 922 and HAF X . The HAF 932 has proven to be a highly successful product with all the necessary features for most enthusiasts. The 922 offered a smaller version of the 932 still fully decked with the necessary features but at a lower price point. Then came the HAF X designed to run anything and everything you could possibly want in your tower. Big motherboard, 4-SLI, USB 3.0, 100 hard drives? No problem for the HAF X. Finally comes the HAF 912 to reach the untapped area of budget computing.

Hitting the sweet spot in budget computing can always be a challenge. This has been especially true with the last few generations of video cards, but is generally true for all products. What features will builders be willing to forgo and what features will make the difference between a success and a flop?

It seems that Cooler Master's approach with the HAF 912 is to offer as much flexibility and affordability as possible. They wanted to provide as many features of the HAF series while keeping the price point as low as possible. Since the HAF series is based on performance cooling I expect to see this core component left untouched. It makes sense to keep the features which are used frequently or non-stop while trimming off the stuff that doesn't provide real benefit or only gets used infrequently. Below is a macro view of what's contained in the HAF 912.

# A little measurement?ehume 2010-09-05 19:35
Generally nice review. One thing I would like to see all reviewers start doing is to measure the distance from the back of the motherboard tray to the panel behind it (the right panel in this case). CM states there is 16mm back there, but an actual measurement would help.

I really like the look of this case. Like I say in all yuor case reviews, none beat the look of the 830 Stacker. One big issue for me is that the Stacker series cases have a mesh cover on both sides of the case, completely hiding the side fans. I hate the unfinished look of a side port right in the middle of the sides of any case. They look like a #ty mode to me. Nice review though.

Seems like a good mid-range case. Cases are one of the few items in a build that can be tweaked or modified. I've never tried to mod a hard drive for example. But for $3.00 I picked up a package of ten thumbscrews (had a choice of colors at that) and made my mid-tower somewhat more tool-less. Another $15 for a 120mm fan moved my air around substantially better. Kinda makes you wonder, what with purchasing scale and all, whether a couple of bucks of features in the HAF 912 up front would have pushed this case over some price point they didn't want to cross?

I suspect the choice to install the modular drive bay put them right near the edge of their projected profit margin, and that they just couldn't afford to add the few extras and miss out on the $60 price point. And when looking at the competition, the modular bay is one major thing that sets the case apart, so it may have been the better choice.

Took mine to its first LAN party; one arm carry. It's nice to carry something smallish and still have the fastest rig.

# Case height?ladyfox 2010-09-07 14:11
I know the dimensions list the height as 18.9 inches but is that from the lowest portion of the case at the top or the highest?

Highest. That is the maximum vertical length of the case.
