5 out of 5 eggsOutstanding Value

This review is from: Cooler Master HAF 912 - Mid Tower Computer Case with High Airflow, Supporting up to Six 120mm Fans and USB 3.0

Pros: This is a well constructed case with plenty of room and ability to configure for various needs. The surfaces and edges are well finished unlike some other cases at this price range ($59.99). I'll be coming back!

Cons: No Problems

Other Thoughts: I had bought another case from a different vendor and returned it because the fit and finish were poor. I happened on this one by chance and highly recommend it.

5 out of 5 eggsSuspiciously awesome!

This review is from: Cooler Master HAF 912 - Mid Tower Computer Case with High Airflow, Supporting up to Six 120mm Fans and USB 3.0

Pros: This is the case into which my first computer build has gone, and the roominess, attention to detail, and super quiet fans have made me a not-so-quiet fan of this manufacturer.

Cons: None.

Other Thoughts: It's roomy enough that I could practically hide in it if bad guys start banging down my door. It has so many cool features that you might as well paint it Swiss Army red. For my first computer build, I had a couple engineering buddies over, just in case. They waxed poetically over this case, and were chomping at the bit as I slowly, methodically, put my first computer together, like it was a cadaver they couldn't wait to stick their hands into.

5 out of 5 eggsVery complete and thought out case.

This review is from: Cooler Master HAF 912 - Mid Tower Computer Case with High Airflow, Supporting up to Six 120mm Fans and USB 3.0

Pros: Has a lot of great features.
Lot's of storage space.
Easy to use.

Cons: Not painted on the inside.

Other Thoughts: I didn't need the HDD Cage so I removed it to increase air flow.
After 2 200mm fans, temps will never be a problem.

4 out of 5 eggsits cheap, but still great

This review is from: Cooler Master HAF 912 - Mid Tower Computer Case with High Airflow, Supporting up to Six 120mm Fans and USB 3.0

Pros: the 2 fans work pretty well, high airflow, plenty of space and room. used for my first build, full atx mobo. it will fit Cooler Master Hyper 212 EVO cpu fan with very little issues does have room on the back for mounting. just enough room to fit all of the wires, also low price for a ton of case. looks awesome.

Cons: its cheap, so some of the parts are cheap. thats expected. just barely enough room to fit all the wires in the back to get the back on, will have to do some management to get them all in there properly.

Other Thoughts: good first case, seems sturdy. its cheap so anyone looking for a decent case with plenty of room for expansion look no further.

4 out of 5 eggsA lot of cheap and flimsy components. Get what you pay for.

This review is from: Cooler Master HAF 912 - Mid Tower Computer Case with High Airflow, Supporting up to Six 120mm Fans and USB 3.0

Pros: -Very customizable
-Great air flow
-Nice means of cable management
-Looks good

Cons: -Super flimsy parts
The front compartment that houses the audio jacks, usb ports, and power/reset switches was really loose. When I'd push a usb cable into it the whole compartment would move back. Audio jacks were impossible to to plug in without holding it in place. I finally opened up the compartment and found that all of the plastic pieces that kept it in place were broken.
Also, when I was removing the front bezel one of the plastic pieces that kept it in place snapped off. I was not remotely forceful.
I guess I'll try to super glue it all into place.

Other Thoughts: I'd return the case, but I threw away the box and mixed up all of its screws and such with my motherboard's. So be warned: Keep every component of the packaging until you're certain the product isn't broken.

5 out of 5 eggsWell worth the money

This review is from: Cooler Master HAF 912 - Mid Tower Computer Case with High Airflow, Supporting up to Six 120mm Fans and USB 3.0

Pros: Even though this is not a full size case , it has plenty of room for the parts and the hands. It accepts a full size motherboard ,no problem. It comes with some gizmos that make installation easier and the inner design is much improved over just a few years ago. Outstanding price!

Cons: The power button is at the top of the case and the dvd drives are in the middle. I turned the machine off a couple of times by accident before I got used to the change. That's progress.

Other Thoughts: The cost of a full size case is prohibitive. I will buy this case again if I need another. Or maybe just for the fun of it.

3 out of 5 eggs Nice looking case but...

This review is from: Cooler Master HAF 912 - Mid Tower Computer Case with High Airflow, Supporting up to Six 120mm Fans and USB 3.0

Pros: Looks great

Plenty of space and mounting options for drives, fans, radiator etc.

MOSTLY Tool free design

Cons: Construction of the chassis is somewhat flimsier than I would have expected. Back panel VERY flimsy...see below in other thoughts.
Front power LED annoyingly bright red, unplugged within 5 minutes of installation.

Front filter not removable, must remove entire front panel of case, which involves removing both sides (one of which has thumb screws, the other does not...why??)

Manufacturing tolerances seem a bit...loose. Side panel sags a bit, leaving a noticeably annoying gap between top panel and side panel.

Removable 2.5" HDD cage...not 2.5". Drives fit, but the top drive has about 1/8" total gap between the 2 sides, it fits and screws down to the mounting holes, but looks stupid as the sides are not square to the top of the cage.

Non-removable motherboard tray (nit picking on this one I know)

Front fan cable is rather short.

Other Thoughts: Case arrived with back panel caved in near I/O shield hole. No damage to box or foam inserts makes me believe this was damaged in the factory. This made snapping the I/O shield into the panel difficult and not fit properly, even after bending the panel back into some sort of straightness. This does not lend itself to a warm and fuzzy feeling knowing that this back panel is responsible for supporting my large graphics card.

IMHO, buy a corsair graphite series instead.
