5 out of 5 eggsNice case

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

Pros: Bought this case because it was one of the highest rated cases here and because of the price ($50 after MIR). Very spacious, had no issues with the mobo install. I built a computer last year with a Rosewill case and had a heck of a time getting the i/o panel to line up properly. This case had none of those issues.

Cons: This seems to be an issue for me no matter what case I buy. The right side, where you route and hide most of your cabling, why cant they just give us an extra half inch of space??? Even on this HAF 912, I had a difficult time getting the side panel on because there is so much wire behind it. I still give the case 5 eggs even though this was an issue for me. Im not that meticulous about zip tying things, but just give us an extra half inch of width, This would have solved all my problems.

5 out of 5 eggsFantastic Purchase - Highly Recommended

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

Pros: Pretty much everything.
- The case is very solid, no lose/rattling parts, I wouldn't be surprised if it withstood my chainsaw. (just kidding)
- The case comes with ample amount of parts. I think this will be the first time I actually have a product where I will never be using the extra parts, because there are so many of them (a good thing)
- The aesthetics suit my liking fairly well. There aren't any fancy LED's stretching across the whole case, or a fancy clear side panel, but for a value case, I am happy.
- The airflow is amazing. No complaints at all. Stress tested it using speed fan and played Battlefield 4 max setting for 2 hours, skyrim max settings for 2 hours, and some other games. Temps stayed below 40C
- The case had plenty of room, as it fit 3 HDD's, a solid state, crossfire GPU'S and my hyper Evo 212 with 2 fans on each side of the heatsinc! (which is a first for me). But it is not ever sized either.
- If the rating went up to 1000, I would choose a 1000. Case is HIGHLY recommended!

Cons: While on my morning train to work, for about 30 minutes, I tried to think of a con to put up. The only thing I could think of was that the zip ties were too small.

5 out of 5 eggsThis case allowed me to create a cool and quiet machine

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

Pros: Easily the best case for 60$

I built two machines using this case and both were fun to work in not a hassle.

Can hide the wires from the power supply

Can take out the hard drive bay for more airflow which is what I did

Comes with a SSD bracket (really comes with a lot of extra goodies for those just in case moments)

Supports 2 200nm fans which is what I bought for both machines (coolermaster megaflow is fantastic)

Cons: USB 2.0 still

The 2 fans it comes with are not enough unless you have a lower temp CPU and the fans are real loud at full load.

Other Thoughts: Lots of room to work in and I think it’s a great case for the money.

Also the case is so big that all my fans actually turn off when doing normal things with the stock Intel heat-sink(with a smaller case heat was trapped more). My board stays at 42C as well.

Power supply: Corsair 750watt RM fan never turned on since I use 300 watts max in gaming (tested with crysis 3 and a Kill A watt meter)

GPU: GTX 970 MSI fans once again turn off doing light tasks

CPU: I7 4790K Stock heat-sink during gaming and the setup above it reaches 70-80C which is fine and during normal use its at <50C which is when my case fans turn off. Getting a 212+ cooler with a COUGAR CF-V12H fan so it can stay very quiet.

I’m writing this review for someone if they want a cool and extremely quiet machine they know where to look. Also I know many will disagree but I don’t like flashy cases so spending the extra 40$ on the fans was still 100$ and I don’t get that type of cooling with any other case. Keep in mind the bigger the fan the more CFM that can come in with less sound.

5 out of 5 eggsReal Nice Case

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

Pros: - Good airflow
- Very solid design
- Easy access to everything
- Comes with HDD brackets, very easy installation
- Includes a set of HDD brackets for every drive bay
- Includes adapter for 2.5in HDD. Great for SSD's
- Solid power and reset button
- Easy setup, cable management
- Awesome price

Cons: - Case does not show off all my LED's

- Lacks a good location for little stickers that come with a CPU

Other Thoughts: My friend has a HAF case. After inspecting his and seeing how it has stood the test of time, I decided to purchase one. He has had his for about 2 years. Neither of us have had issues setting it up or maintaining it.
