1 out of 5 eggsMissing hardware

Pros: No sharp edges, not too bad a looking. The fan that ships with it is quiet.

Cons: MISSING HARDWARE!! Did not come with the plastic drive rails and screws. Someone messed up the at the plant and did not put them in the box, it was sealed when I got it. I was able to mount my 2.5" SSD but the 3.25" drive is mounted with only one screw. Drive cages are not removable. The 3.5" inch bay is riveted to the bottom. The 2.5" bay is removable but uses square head screws I did not have one so adding the fans was an exercise in patience. I needed to add two fans on the front. The fan mounting holes are not standard, they are too small. I had to buy bolts/nuts/washers to mount them. The front panel is two pieces and the top piece 5.25" external drive bay cover constantly falls in to the case. Really a pain, I had to tape it into place.

Other Thoughts: The case was a disappointment and.was missing necessary hardware. Pick a different one.

5 out of 5 eggsWay better than what I paid for

Pros: Normally, you get what you pay for with these things, but in this case, I am pretty impressed with the quality.

It is sturdy, has lots of space, and just the right number of 5.25" bays. (It actually has three, but one is taken up and concealed by the front panel.)

Also, it was _really_ cheap when I got it on sale, for only $30 (not even counting the $10 rebate available at the time I got it.)

Cons: The front panel has only one USB 3.0 port. Seriously, there should never be an odd number of USB 3.0 ports except on laptops. Odd numbers of 2.0 ports are not quite as bad, I just don't like wasting an entire 3.0 header on my mobo and getting only 1 port out of it.

Everything in this computer goes together with screws, so make sure you have a real screwdriver before you get it. I don't mind -- I actually like it -- but some people seem to be really into those tool-less cases.

There is no simple way to prevent unauthorized access to the inside of the case. Other cases I have used included a small tab that you could put a padlock through, but this cases doesn't have such a feature. It also doesn't have anywhere to mount a chassis intrusion detection switch.

I had a small issue getting the front panel audio to work, but today it just started working, so I am satisfied.

Other Thoughts: This case did not resolve an issue I had in my previous case (the rear IO panel was slightly misaligned with some of the USB ports) leading me to conclude that that problem was the fault of the motherboard, not the case.

3 out of 5 eggsMissing parts

Pros: -Case is rather solid for the price
-Front IO works well
-Visually Appealing
-Room for more fans

Cons: -Locations of holes for cable management could have been better (like the CPU slot)
-Case did not come with latches for the 3.5" and 5.25" drive bays
-Standoffs are poorly placed for an ATX board
-Front Mount fans do not use standard fan screws
-Screws are specified with their use

Other Thoughts: For only $40USD, I can't complain that much, you get what you pay for I guess :/ . The RAIDMAX side does not appear to sell the screw less mounts either.

Manufacturer Response:

5 out of 5 eggsAwesome Mid-Tower!

Pros: Lightweight, Easy Access, Great Mid-Range Gaming Case

Cons: Power LED & Power Switch cables too short (though the HDD LED & Reset Switch cables are just fine).

Other Thoughts: Absolutely fantastic, low cost case. Bought 5 of these to build new gaming rigs for the entire family. Easy access to every angle of the PC. Plenty of room for everything except the largest of high-end video cards... even has room for those if you remove the 2.5" tray.

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.
