5 out of 5 eggsGreat Case for Any Build

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

Pros: A great size for about anything you would want to build. Ample room for any cooling setup. Not a bad look either. Comes with sufficient accessories to complete the build. Good pricing point especially when you can get a rebate or find on sale.

Cons: I've completed two builds in this model case over a four-year period. It's time to put USB 3.0 outputs in the front.

5 out of 5 eggspopular case for a reason

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

Pros: -great room for cable management, definitely enough tie-down spots.

-easily removable/Turnable HDD bracket was a huge plus, even though it did fit my MSI Gtx 970.

-very clear instruction manual, I was a first time builder and definitely appreciated this.

Cons: Can't think of anything.

Other Thoughts: There's an etched table inside the case listing Motherboard types and the mounting screw locations for each. It was incorrect in leaving out the "G" location for ATX.

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

Pros: Plenty of room, low cost, good air flow, well made, solid.

Cons: The only con I have to say about the case, is I wish I was able to do better cable management. But that more then likely my fault.

5 out of 5 eggs***Great Case***

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

Pros: Easy to Work With
Well Made
Moves Plenty of Air
Large for a Mid Tower
Umpteen Ways To Modify Front Panels for USB3.0,DVD/CD Combo etc

Cons: I/O Plate fit funky
Removal of HDD Caddy for GFX Leaves Scant Room For More Than 3 HDD
Had to Remove SSD Tray So 850w PSU Modulars Would Fit

Other Thoughts: If you're on a budget or just plain budget minded and wanna get something to base a good barebone build on you certainly won't go wrong here. Sure it doesn't have a DVD Combo or Front USB3.0 but hey won't break the bank and you can choose whats better for you in that department. Highly Recommend.

1 out of 5 eggsGrounding problem

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

Pros: After the money wasted on replacing parts, none.

Cons: 6 Months researching what was causing all peripherals to disconnect, distort, and crash... Along with the money we wasted on repair shop diagnostic fees and "repairs", RMAing my GPU, PSU and motherboard- not once but twice thinking that the company must of made a mistake in troubleshooting cause I thought it had to be the motherboard causing all my crashing, the last 2 repair shops I went to agreed it had to be a faulty motherboard, I've replaced all other parts so why not. I gave up on getting a replacement motherboard from them and went ahead and bought a new one from a different company.. So after 6 months of trial and error, money wasted, and no games being played as well of work being slowed down this new motherboard worked for 2 hours, then made and eerie I've never heard before, emitted smoke from the case, then lit a flame that came out of the chassis from the top. Needless to say, I lost the most expensive parts of my build, my CPU, GPU, PSU and motherboard. So I come here to recheck reviews because 5 eggs to me, meant good enough to buy, also I've never had problems with computer cases before. From what I've gathered via reviews and message boards this case has grounding problems and I have wasted time and money replacing other parts instead of this case.

Other Thoughts: Worried if replacement were to be sent I'd just end up losing more parts to fires, may end up looking for a different case

Manufacturer Response:

Good Morning Juan,

I apologize for the inconvenience as there can be several reasons a short can occur from extra stand-offs touching the back of your motherboard to a loose ground from the IO panel that was accidently removed when installing the system and several other factors. I assure all our end users if you're experiencing this issue please reach out to us directly through our CM Fanzone via Live Chat, Support Ticket, or phones for an immediate resolution.

I look forward to your response.

Regards,
Felinni M.

5 out of 5 eggsHAF

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

Pros: This beast of a case hid every single one of my gigantic non-modular PSUs cables and made it look nice and tidy. It may not be painted inside but who really cares when you buy a product this functional for this price. One of the best computer parts buys of my professional career for the money. Just the extra real-estate and top notch cable management (allowing for better airflow as well ) matched with great fan ports, gave me around ten percent better Firestrike benchmarks! With the removable drive bay, this jawn swallowed up my huge three fan windforce Gigabyte 970 GTX very easily. Don't buy anything else in the same price range trust me.

Cons: No USB 3.0, but ill just add a header.

Other Thoughts: Do it.
