2 out of 5 eggsNice case, when arrived intact...

Pros: front USB 3.0, mesh bezel, decent budget case, comes with front USB 2.0 adapter for older motherboards (unlike the Corsair 200R)

Cons: not as good as other Antec cases, somewhat flimsy, Antec QC needs to change their foam inserts because it doesn't protect the case at all

Other Thoughts: I bought this case 2 years ago when it first came out and liked it enough for a custom built computer. Decided to use same case again for another custom build. This time, the case was heavily damaged like I've never seen before. The front bezel tabs were all broken so the bezel itself was floating around the box. The drive bay covers all fell off back into the case. The steel part behind the bezel was badly bent. Surprisingly, the box showed little signs of damage. I think the culprit was actually the foam inserts to protect the case. They are too flimsy and flexible unlike rigid styrofoam, which might have kept the case from being as damaged as it was. It's unfortunate and hopefully Antec QC will address this issue or they will be receiving a lot of returns from their distributors.

5 out of 5 eggsBest All-Around Budget Build Case

Pros: Great price for what you get. The case breathes as well as any high end gaming rig would hope for, It comes with two fans, the PSU can mount facing up OR down on the bottom, there's plenty of room for more fans in various setups. The mounting brackets make installation a breeze. It's painted throughout, with no unpainted steel/aluminum to speak of.

It's a near perfect design for anyone wanting to look good, but not go crazy. Stylish enough for a gamer, professional enough for a business, and toned down enough for Grandma.

Cons: I truly wish it had either a bottom or front fan as well, but that's hardly a complaint. It's just a wish.

Other Thoughts: I've taken to buying these exclusively for all of my PC builds unless I'm specifically asked to use another one.

Functionally, it's an absolute breeze to setup, regardless of the parts used. I've never once gotten a complaint about the looks, in fact I'm usually complimented on my taste in cases, due to it not being too much or too little of anything.

Well done, Antec. Fantastic product.

5 out of 5 eggsNice case for the pirce

Pros: 1. High Quality Materials
2. Quiet fans with good cooling
3. Lots of room to work with

Cons: 1. Plastic in front :(

Other Thoughts: Although the plastic in front is kind of cheap, the rest of the case makes up for it in the end...

4 out of 5 eggsAmazing for the price.

Pros: Enough drive rails for 5 drives.
Good space on the back for cable routing.
Filtered Intake for the PSU.
A pretty nice 2.5" SSD mounting idea (at least it didn't go unaddressed)
Good Packing material. I heard the delivery guy drop it at the door and the foam choice probably kept it from getting dented.

Cons: Pretty light
The feet on mine are uneven
The fans are all installed as exhaust
No front panel filter for the fans

Other Thoughts: I bought this for a new 4 drive NAS project, and I think it'll serve that purpose quite well.
I have no heavy criticism at all, most of it is nit picky stuff, I'd definitely use this case for a smaller gaming PC as well.

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.
