5 out of 5 eggsGreat case

This review is from: Cooler Master HAF 912 RC-912-KKN1 - High Air Flow Mid Tower Computer Case

Pros: For the budget minded who wants a quality case...this is it! Some cases in this price range are a bit "flimsy" ..not the 912! Its a very sturdy case. has all the quality features one comes to expect from Cooler Master. the 912 will handle the 212 plus CPU cooler, or the H50 water cooler, and easily takes the EVGA 960 video card

Cons: There are no real cons for this case Some might say it lacks fans, if more fans is your wish buy the 922! or add your favorite fans

Other Thoughts: The 912 will handle all your peripherals. I simply take the supplied front fan and place it on the side door then buy 2 Cooler Master 200mm fans, one for the top and one for the front. This gives you more than enough air to cool even a "hot" machine.

5 out of 5 eggsLooking For A Good Budget Case?

This review is from: Cooler Master HAF 912 RC-912-KKN1 - High Air Flow Mid Tower Computer Case

Pros: Yes, I know this case is quite old at this point. However, unlike some old cases, it doesn't feel cheap and isn't lacking anything that people actually need. Almost like CM knew 2015 was coming. The case supports a good amount of watercooling. You can fit 1 240mm Rad at the top and 1 120mm at the back without modding. However, I would mod this to have a new paint job, a window, and a reservoir and pump mounting spots. For $60 I would recommend this case.

Cons: The only problems I have are the awful PSU filter, not so neat cable management, (still decent) No interior paint (even for an OLD Case). Thats it.

Other Thoughts: I will be buying this case Again to mod it and see what I can make.

5 out of 5 eggsAwesome Case

This review is from: Cooler Master HAF 912 RC-912-KKN1 - High Air Flow Mid Tower Computer Case

Pros: The cable routing options are excellent in this case as it has a raised platform that the motherboard sits on so you can run cables behind it, there is also a cut-out behind the cpu to assist with mounting your cooling solution... you can also remove the middle HDD cage for better air flow and it looks cool.

Cons: I haven't tested this but I read in someones review and verified by measuring my case that this will not take most full sized liquid coolers (corsair h100i) without modifications, so I ended up getting a smaller cooler instead.

Other Thoughts: really a great case and when I get my liquid cooler in the mail (intel) i'll be able to decide if my only con was a con or not.

5 out of 5 eggsAwesome case for value

This review is from: Cooler Master HAF 912 RC-912-KKN1 - High Air Flow Mid Tower Computer Case

Pros: Very roomy case, plenty of room for most PC builds. With removable drive cage can accommodate some of the larger video cards like my EVGA 980 GTX.

Very solid yet lightweight build, no sharp edges or anything to get hung up on during build. Has knockouts for water cooling and everything you need for good cable management.

Cons: The only thing I wish they would change is to put the USB and headphone / mic jacks below all the DVD drive bays. When I have my headphones plugged in to the front the wires hang down in front of the drive bay. It seems most case mfg. are doing this now, seems kind of silly to me that they would design this way.

Other Thoughts: Great case for a great price. Keeps my systems plenty cool, I have done 3 builds in a row with this case. The first was back in 2009 and this recent one was April 2015. My entire family has this same case now because it works so well!

5 out of 5 eggsLots of room

This review is from: Cooler Master HAF 912 RC-912-KKN1 - High Air Flow Mid Tower Computer Case

Pros: Plenty of room for some really good airflow. Comes with 2 120mm fans from Coolermaster. Has enough options for a top mount, 120mm, 140mm, or 200mm. I put 2 120mm in the top and one more on the side and this baby moves some air, right now according to cpuid hwmonitor my fx4170 is between 6c and 21c, mostly down around 12 - 15c. MB is at 31c and my gtx750 is at 29c. both are mildly oc'd. Easy to remove the plastic faceplate, finally someone used their head for something other than a hat rack, Personally I cant say enough good things about this case. CoolerMaster out did themselves and the other case manufactures with this one.

Cons: Just one but it's no real big deal. make sure your mb plugin has a long cable otherwise you won't be able to run it behind the mb. Mine just runs straight up the mb to the plugin, like I said no real big deal.

Other Thoughts: If it lasts as long as the Rosewill I bought in 2008, I will be one happy camper. But it is a good looking case. btw, the Rosewill case is still going strong but my g/f kinda latched on to it and I havent been able to get it back yet.
The only thing that I can think of that would make this case any better is for the mb and case manufactures get together and come up with a standard for hooking up the power switch, reset, hd light and power light to make them into 1 plug. I am 54 and I don't see as well as I used to, some of the print on the mb I had to take and put my reading glasses on, get a magnifying glass and a flashlight to see, still and yet most of it was guess work on what it said.

4 out of 5 eggsMy first case, and it's been great

This review is from: Cooler Master HAF 912 RC-912-KKN1 - High Air Flow Mid Tower Computer Case

Pros: Lots of fan options. Plenty of room to do what you need to do for your build. Very sturdy, haven't worried about the structure. The black paint job on the outside is nice, the HAF logo on the side is pretty neat.

Cons: Interior isn't black, dust filtration is mediocre, could've done without one of the HDD cages (see other thoughts), no rubber grommets for cable management.

5 out of 5 eggsbest buy under 100$

This review is from: Cooler Master HAF 912 RC-912-KKN1 - High Air Flow Mid Tower Computer Case

Pros: roomy enough to take massive video cards and hsf and still have room to work in. sturdy construction. easy to mod. great airflow with a few cheap fans

Cons: no usb 3.0, bottom hard drive cage not removable unless you cut the rivets

Other Thoughts: removed bothe the hard drive cages and moved my 3.5" 1gb standard hd into the 5.25 bay to open up airflow at the bottom front of the case.. with 3 relatively cheap fans (2 in, 1 @ front and 1 @ side, 1 out @ top) this baby has plenty of airflow

This review is from: Cooler Master HAF 912 RC-912-KKN1 - High Air Flow Mid Tower Computer Case

Pros: Great airflow and multiple fan placement options. Cable management is decent and although there are no rubber bushings it didn't have any sharp edges to contend with.

Cons: None

Other Thoughts: Have used this case for 2 builds now, running as many as 7 fans but still nearly silent. Best case for the money, whether it's a budget build or performance this case works great.

5 out of 5 eggsGreat Case

This review is from: Cooler Master HAF 912 RC-912-KKN1 - High Air Flow Mid Tower Computer Case

Pros: Lots of room to work. Comes with tons of extra hardware. Cable management was a breeze. No sharp edges to cut yourself on. Front panel wires are a good length.

Cons: None.

Other Thoughts: I highly recommend this case, easily in my top 3 cases from here on out. I am not sure how well the 2 stock 120mm fans would have worked, as I immediately upgraded them to 2 200mm fans.
