5 out of 5 eggsSolid case, just what I needed

Pros: Plenty of space inside for cable runs.
USB 3 on the front.
Actually useful screwless drive bays.
Can easily put a 2.5" drive in without any fuss.
Comes with two quiet fans.
Bottom mounted PSU. Looks cleaner and easier to get to everything else.
Had room for my unexpectedly huge heatsink (Cooler Master Hyper 212).
No goofy stuff or windows, just a clean case.

Cons: Only real con is that the space for cables makes it wider than I expected, but only in this sort of bulge it has on each side. So be careful if you have limited space, fortunately I don't.
Non-con: Wouldn't last if I dropped it down the stairs. To be clear, this thing is sitting on the floor and will be until I recycle it in 10 years or so, so it really doesn't need to go through war... It's sturdy enough for what I need, and that's great.

Other Thoughts: It's really hard to find cases on this site. People have odd standards it seems... It's sturdy enough, yeah it's not a tank, but do you need one? For the price, you can't beat this. It looks slick and classy, and holds everything you need.

2 out of 5 eggsWorked For a Month

Pros: Its cheap

Cons: Its cheap. The power switch seems to have died after only about a months use. I contacted Antec via phone and was told they would mail one out the next day. Still haven't received it.

Other Thoughts: This situation is upsetting as I have always had great experiences with Antec gear. They were my goto company for friends and family need cases or even psu's. Might have to rethink that going forward as this power switch issue seems to be fairly common.

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
