3 out of 5 eggsMissing parts, low quality design.

Pros: It is mostly metal, with only the front panel being plastic. It comes with a mobo speaker, many extra screws, and a mobo stand off.

Cons: The case I received did not have any tool less latches for the 5.25" or for the 3.5" bays. It also only comes with one fan mounted on the rear (which I knew when purchasing). However the front mounts for fans require small screws, which means not only did the screw not work that came with my extra fan, but I also couldn't transfer the back fan to the front since the mount holes are different sizes.

Other Thoughts: The packaging the case comes in is also pretty weak, only being wrapped in clear plastic and then covered on the front and back with hard foam. Mine did arrive undamaged however.

4 out of 5 eggsGood Case for the Price

Pros: Nice industrial kind of look to the case. Has good cable management. Thumb screws on the back make for easy removal of side panels. I also mounted two additional 120mm blue LED fans on the front intake that give a very nice blue color to the front of the case once the plastic and mesh covers were put back on.

Cons: Instructions are vague and can be difficult to understand.

Comes with only one set of case fan screws for a case designed to have two case fans mounted on the front for air intake. See Other Thoughts section.

Mesh screen on the front where you would mount an optical drive can be easily pushed over. This is annoying if you just booted your computer and have to shut it down in order to realign the mesh cover.

If you want to use a liquid cooler in your build (As I did) you must use a single radiator cooler mounted to the back (exhaust) of the case. The top of the case is somewhat domed which does not allow for a radiator to mount to the top. I simply relocated the included rear fan to the top mount. Also the top only has mount for one fan. Does not have mounts or even vent holes for two fans.

Other Thoughts: Hardware screws are all in one bag with no labeling and nothing in the instructions to indicate which screws are for case fans (Four Long screws with short threads) and which ones are for devices.Go to hardware store and get a bag of screws that are same dimensions as the long screws for about $2 and you'll be fine.

Other than the little things that I listed in the cons section which I consider mostly minor, I like the overall design of the case and it's ease of functionality.

4 out of 5 eggsCapable Case for a budget builder

Pros: Spacious case for mATX boards. Four spots to place 120 mm fans. 3 slots for hard drives. You could through a ssd in the bottom portion of the case because there is a lot of room. Quality build for the price. Two 5 1/2 bays for dvd drives and other devices. Front panel audio/mic plus usb 3.0 and usb 2.0. Removable front panel to install two fans (part of the 4 mentioned above).

Cons: Not ideal for full ATX boards. It's a little too small for them. If you need to install two dvd drives it may be a little cramped for the connectors to the front panel. The front mesh in front of the two exterior fans gets dusty really fast, like within a week I have a white film, though this may be my carpet's fault and always running fans lol. Doesn't come with easy remove hard drive bays like it shows on the box and manual. Side panel is kinda cheap. Kinda cramed for cable management.

Other Thoughts: If you need a cheap case I highly recommend this one. It has its faults but you get what you pay for. The front panel ports are nice. The bottom cover can be pulled off to install two 120 mm fans. I recommend getting two with blue leds so u can have a cool looking front. The case only comes with 4 of the screws for those two front fans so I used two on each fan in the top left and right corners and it works fine. The fans wont get dirty but the cover in front will. Just brush your hand to wipe it off. If you need a budget case that can accomodate a large gpu and a matx board then this is your case. The packaging was great. I recommend getting a small screwdriver cause the weird angle makes mobo standoffs dificult to install on. THe standoffs are already put in the case. All except one of the expansion covers are break off ones which sucks, but oh well. The filter for the psu falls off alot but just put it back on is no prob. If you need a sub 50 buck case then get this one. Dont get it if u wnat full atx

GET A MODULAR PSU for cable management.

4 out of 5 eggsgreat airflow - roomy - slight fault in wire managing

Pros: -Great airflow for the size
-top 120mm fan slot actually fits a fan
-Roomy for the size, fits a full sized graphics card

Cons: -Wire management isn't too bad, however there is no way to get wires from the back to the top of the case, the only way to route the 8 pin cpu plug was through the wire management slit located at the top right corner of the motherboard. So it's stretching across.

4 out of 5 eggsNice case - lots of fans

Pros: Plenty of cooling fans, lots of disk drive space.

Cons: Hard drive bay at bottom of case is problematic. The length of most SATA power and data cables are such that the disk slots in the front and possibly the middle are longer than most standard cable lengths that come with modular power supplies.

Another issue is the fan mount on the side of the case. It takes an odd size fan (160mm) which are hard to find. I then tried a 80mm fan by relocating the rubber mounting grommets. However, the CPU cooling fan heat sink (a standard sized - vertically mounted Coolmaster) is just high enough to intrude into the fan. Gave up at that point. However, additional fans are not really required as the factory installed units are more than adequate to cool everything.

Other Thoughts: Overall, for the price and what you get it is well worth it.

5 out of 5 eggsGreat Case For Price

Pros: -Sturdy where it counts.
-Dust filters on all intake fans.
-USB 3.0
-Bottom PSU with vent.
-2.5" bay, a must these days.
-Easy front panel removal.
-Cable management.

Cons: -Only comes with 1 out of the 4 optional fan slots.
-Non-standard fan screws "see below".

Other Thoughts: This is a pretty good case for its price, I'm really happy with this purchase. It came with all the case screws I needed, it has dust filters on all the intake fan slots, it seems sturdy enough where you need it, only thin parts I noticed was around the addon card slots, and the front panel comes off really easily when you need to install extra fans.

One of the biggest complaints I've noticed people saying here is the fan screw holes need to be drilled out, this is actually not needed because the case comes with its own custom fan screws that allow you to install the fans from the opposite end (long screws), it uses its own thread size so you cannot use standard size fan screws in these holes, the only downside is though it doesn't come with enough screws to install all 3 extra fans so unless you can find these screws somewhere else then yes you will have to drill out the holes.

Other then that I really like this case, the cable management is pretty good too, it fit my micro atx perfectly fine, can't comment on full atx. And the only other negative I would say is that it doesn't seem to come with enough fans, it especially doesn't come with the ones it shows in the picture, it only comes with 1 rear 120mm fan, any other ones you will have to buy extra.

4 out of 5 eggsFrustrating, but worth the effort

Pros: Looks are a large pro. I love the overall design of it
Ample room, as others have stated, especially if you have a Micro ATX board.
Lots of space for drives
Large hole in the mobo mounting tray for cooler brackets if need be
Option to mount a radiator in the back
Excellent airflow

Cons: Poorly labelled screws
Poorly designed standoffs/standoff mounting points
Drive Cages are very tight,
when connected to Molex power, the rear fan is a touch loud
While the kickout on the side panel for wiring helps, it is nowhere near large enough where it needs to be.

Other Thoughts: Okay, let's start with the bad. I spent two days trying to diagnose why my computer, which worked fine in its old case, wouldn't turn on in this one. Turns out it was a simple mistake on my part, so no big deal. But, there are other negatives which compounded the situation.

First off, the standoffs are either poorly machined, the mounting tray isn't good enough for them, or, most accurately the screws provided aren't labelled. At all. Thanks to trial and error on my end, I have three standoffs which just spin about under the motherboard when you try to put ANY screw in them. On top of that, the standoffs aren't exactly centered in the holes, despite my best efforts to make sure the board was centered on them. Very disappointing.

Second, the drive cages, as mentioned, are a bit of a tight fit, particularly for the 3.5" drives. When installing my 1tb Seagate, it was such a tight fit that I ended up accidentally applying too much pressure to the drive, and it shot out the other "oh ****" moment.

Finally, the 120mm fan, due to my mobo's lack of fan headers for it, is being powered by a molex power cable from my power supply. Which, that's a positive, that the fan came with molex power preattached. Good on them, made wiring the fan up easy for those of us with limited fan headers.

And now, this is just me, but I use my Front panel. A lot. My old case had 4 front USBs, and all of them were in use. That's just the nature of how I work. This case only has two front USBs, and well, this has caused some issues. I'm going to look into getting a drive-bay mounted USB hub down the road, but it would be nice if the case had maybe just one more front USB port.

Now, that's the negative. Let's move onto the positive.

The case, overall, looks great. For a steel and plastic case, the fit and finish is quite good. I love the rugged, louvered look of the front. The kickouts for the wiring storage, while helpful, could be a touch bit wider towards the know, where your drives would be wired up at, and where your power cables for your motherboard come and go through?

But, with my Micro ATX board, my R9 280, and my Cooler Master TX-3 with dual 90mm fans, this machine has seriously not run cooler. Its old case was much smaller. But this case has so much room inside to work, so much room to upgrade down the road, and the price, while in the end it reflected the quality of the product, the price was still more than good enough to make it a good case for a budget build.

Would I recommend this case? Maybe. If the person asking is like me and doesn't need unnecessary lights, doesn't like asymmetrical case design, and likes things a la Henry Ford, "you can have it any color as long as it's black". But I would have to issue them words of caution in relation to the standoffs, and the drive cages.

5 out of 5 eggsMore than satisfied

Pros: Looks great in and out. For the price I can't see buying a different case. Well constructed. Easy to organize cables. All of the required screws, parts, etc, included. assembly/disassembly is super easy. Its light.

Included a 120mm case fan and space for at least 3 more. Clear side panel.

Cons: none

Other Thoughts: Everything went right in no problem. Plenty of ways to organize the power and other cables. Slots for mounting 2.5" drives and clean cable management.

I am very happy with this case.

3 out of 5 eggsAlright, some issues that could be a problem

Pros: Cheap, looks nice, just enough room to fit my 12.5 in. graphics card

Cons: Front mount fan holes were too small to fit standard size screws so I needed to drill them larger to fit my fans. The front hard drive bay was poorly placed, making it very difficult to mount front fans even with a short screwdriver. Just barely enough room to fit an atx motherboard behind the power supply, but my power supply has rounded corners and it might not fit if they were sharp, so it is very close

Other Thoughts: the cable length was fine, it may have been fixed since earlier reviews or may be a hit or miss thing, the power switch stopped working after about a month and a half, so I connected the reset switch where the power switch should be and can no longer use the reset functionality. I have not tried to contact them because losing the reset switch is a minor inconvenience and I don't think it is worth the time to get it fixed.
