1 out of 5 eggsAvoid, this isn't Antec

Pros: Looks a bit better in person than in pics.
USB 2.0 adapter for front panel.

Cons: Where to start. This is an awful case. Quality Control is non-existent...

Both fans bad out of box. Both clickers. Now in garbage.
Lower SSD mount is too close to side, cables barely fit.
All four thumbscrews were tapped wrong. Have to use screwdriver to remove and replace each time. All four.
Two of six standoffs were stripped.
Two of the four power supply screw holes weren't completely tapped. Had to drill them out. They had started them, just didn't finish them.
HDD mounts are terrible. At least provide a screwhole for us to make them at least somewhat stable.

Other Thoughts: There are 50 cases on Newegg that are less expensive than this case, but are far superior. This is really an awful, cheaply made, case. Antec should be ashamed to put their name on this. If you have to have an Antec, get a 300. It's miles better than this thing. Quality control just doesn't exist here, which is too bad because the basic design is attractive.

Very, Very disappointed.

4 out of 5 eggsGood for the price

Pros: Cheap
Looks good
Plenty of fan mounts
Can fit just about any graphics card and aftermarket CPU cooler without any problems

Cons: Hard drive mounts are pretty bad in general. This won't be a problem if you're using an SSD, but regular hard drives will rattle quite a bit while in use since the toolless bays don't secure them properly. Connecting power cables to more than 2 or 3 hard drives at once may also be a problem depending on the cable configuration of your PSU.

1 out of 5 eggsRubbish

Pros: none

Cons: Cheap, poor construction

Other Thoughts: The cost of this case should be in line with a $15.00 case. I purchase Antec cases for custom builds, most I am quite happy with. This one is a real lemon for the price. I would not recommend this case to anyone, unless it cost $15.00 because that is all its worth.. After freight I had paid $75.00 for this unit

4 out of 5 eggsGreat case

Pros: -Enough room to put just about every video card if you do the cable management right, I recommend getting a modular power supply so no cables will be in the way, or just put them in the drive bays at the front. Not really much space in the side panels to put big cables like molex, the 24 pin from my xfx psu was pretty much impossible to fit. I would get a PSU with flat cables like the corsair RM series.
-Really well priced for what you get, got it for around $50 last August.
-All black, side panels look cool
-Black interior
-Bottom mount for PSU with dust filter

Cons: -Came bent and wobbles easily when on a hard surface, One thumb screw was bent and hard to put in.The metal on the back where the IO shield goes was oddly shaped and bent and I couldnt get it on no matter how hard I tried so now I have no IO shield on the back. Could be blamed on the shipping company though cause the metal is pretty strong and not flimsy.
-Not much room between the side panels for cable management even though the bumps on the side were designed for it lol. Ended up just stuffing them all in the front.

Other Thoughts: Really good case for the price with lots of room and plenty of places for fans, just wish the shipping companies were a little more careful. Could have sent it back but wasn't worth the hassle.

3 out of 5 eggsUpdate

Pros: I thought I would update my review. This case is pretty good for the price. I paid $32.00 for it. I just wanted to let everyone know that it can in fact hold a R9 280X. I have a Club R9 280X install, which is 268mm long. And is has more room than that. I measured around 11 inches, so I would just keep whatever card you install just under 11inches and you will be fine. I couldn't find anything on this anywhere. The website and Newegg states 266mm maximum on graphics cards length. You can go further than that. Also I have a 120mm fan on the side door as well as a Xigmatek Gaia heat sink with plenty of clearance. I have a EVGA NEX750B installed which is a snug fit. Also it blocks you from installing a fan on the bottom of the case. I hope this helps. Here is my build. It cost me 650.00 total.
Antec One case
8Gb Amd 1600 ram
Mushkin 120Gb SSD
2Tb Seagate 5900rpm hd
EVGA NEX750B psu
Xigmatek Gaia heat sink
Asrock Fatal1ty 990FX Killer mobo
Club R9 280X Royal Queen
Amd 8320 cpu

Cons: None for me yet.

3 out of 5 eggsOk but one of the fans was noisy

Pros: Nice looking. Most components easy to install. Delivered in good condition.

Cons: One of the 120mm fans was noisy right out of the box. I could have returned it but just replaced it instead. Also would be better if you didn't have to take the other side of the case off to install hard drives.

5 out of 5 eggsOutstanding case for the price!

Pros: -USB 3.0
-Built in filter

Cons: Could use more drive space

Other Thoughts: I'm using 2 of these, one for my ESXi host and one for my NAS. They work perfectly and give tons of room behind the mainboard for cable management. The airflow in this case is great and provides plenty of options for fans. The only thing I will say is that it could use more drive space but for the price point it's an outstanding value!

5 out of 5 eggsSturdy, Versatile, Stylish, Steel Case

Pros: This case is sturdy, well-built, made of steel, but not too heavy. The fans are very quiet. All of the features have functioned as expected. The case contains three 5.25" bays, five 3.5" bays and two 2.5" bays -- and I used almost all of them. When the case is fully loaded, space is tight, but everything fits okay. One can pass cables behind the plane of the motherboard to get them out of the way. The front panel controls, including the power button, reset button, audio sockets, and two USB3.0 ports are conveniently placed and everything worked. Also, I like this sleek, simple, black styling.

Cons: Tight fit when fully loaded.

Other Thoughts: My build components are as follows:
Antec Gaming Series One black steel case
GIGABYTE GA-Z87X-UD3H motherboard
Intel Core i7-4771 Haswell 3.5GHz LGA 1150 processor

1 out of 5 eggs

Pros: Good looking case on the outside, has USB 3.0 and SSD mounts.

Cons: Bad design for mounting hard drives, you have to take off the opposite side of the case to mount them. Problems with power button. We ordered 3 of these cases and had to return all 3.

Other Thoughts: Very unhappy, Antec dropped the ball on this case! We have always used Antec cases and before this model they were all great quality cases.

Manufacturer Response:
