Cons: None

Other Thoughts: Great product, Cooler Master is imop, one of the best cases you can get, top shelf quality.

5 out of 5 eggspretty good budget 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: Best thing about this case is the amount of room it has on the inside....it seems like a ComputerCasus cavernosus compared to a few atx mid tower boxes I have used before. It's a little bigger on the outside than most but the amount of room to work with on the inside is well worth it. Room to spare....the hyper 212 evo looks positively small in there and it looks like there would be plenty of room for more fans if I ever go there.

Not the thickest metal I've ever seen in a case but seems good enough. For an inexpensive case seems heavy. Nice understated server style look with mesh type front panel. Has the panel connector stuff near the top. Nice subdued red led for power and one red led for hdd. the most recent version has the usb 3 connector on the front along with a usb 2 and a mic and headphone jack. all of the included wires for these are more than long enough. it comes with lots of screws, ties, etc. so in all likelihood you will have lots left over. Instructions kind of sparse but I have built before it is pretty much self-explanatory. lots of tool free strips to install hdds, in fact had lots left over. the case has 2 ways to install ssd...a 2.5 inch cage at the bottom(which can be used to enclose excess psu connectors(example the legacy power connectors) or a plastic caddy that will go into a 3.5 bay.

seems to have options for easy cable management. the cage with 3.5 bays in the middle can be easily removed for more room and air flow. I don't have one of the new really long video cards yet but it looks like it would easily fit. most of the edges inside are rolled. all in all it is about the easiest case to work with that I have seen so far.

Cons: inside not painted. many cases, even half the cost of this one, have black painted interiors. not entirely tool free...to securely attach dvd drive you need two screws as the included quick lock had only one, so the other side had to be screws. not that big a deal though. also had to uncsrew to remove the middle cage. the front fan connector was not long enough to reach motherboard header and so had to use the old style adapter molex thing.

5 out of 5 eggsSolid case for the price

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: - Darn solid construction
- Plenty of room for fans
- Rear grommets for an external cooling loop
- Removable hard drive bay for larger graphics cards
- Screwless hard drive and optical installation
- Plenty of room
- Comes with all the hardware you'll need

Cons: - Not a fan of the big etched HAF on the case door
- Shipped with only one thumbscrew installed (the other one was rattling freely in the case)
- Front dust shields keep falling off
- No cable management

Other Thoughts: Actually didn't expect this case to be so good given it's a Cooler Master (and only $65), but man, it's really nice. Very solid, made of high quality metal, and it looks nice, too. Just kinda wish the HAF logo was on the non-door side.

3 out of 5 eggsThe Case itself is good

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: It wasn't broken

Cons: Both of the fans in this case make an irritating noise under load @ only 900rpm approximately.

I did not notice it immediately, but, after a couple of days using these fans the irritating sounds they were making became obvious.

Also, the wires on the two included case fans are VERY short and I was barely able to connect them to my motherboard fan pins.

Other Thoughts: Yes, but, spend the extra money to buy some good case fans to put in it.

5 out of 5 eggsIt's a 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: Pretty nice looking.
Roomy, it's bigger than I expected, I'm not good at translating specs to real world space.
Slightly more arousing than Penthouse.

Cons: The only reasons I considered knocking an egg off (this is likely not due to Newegg, hence my reluctance) is that my case was VERY SLIGHTLY dented, and the box was also damaged around the handles, indicating to me that it was dropped at least once.

Beyond that, the parts to install devices were...just kinda... in a box floating around inside the case. Couldn't package better than that? I don't know if that's the standard, but when it got here, it wasn't secured in any way whatsoever. Probably more on Cooler Master/FedEx than Newegg, but it's all good. Would recommend to first builders, very little chance of space issues.

Other Thoughts: I would have recommended this to a friend of mine, but he started buying parts before me and ended up with a case that is pretty, but significantly smaller. Ripperoni in pepperonis.
