1 out of 5 eggsOrdered 2; one arrived damaged.

Pros: It would be a good product, if it wasn't damaged.

Cons: Antec quality control is clearly to blame for the damaged unit. As with so many other reviews of their products in recent years, the outer box showed no sign of damaged. The unit inside, though, is badly bent on one rear lower corner, preventing proper mounting of the bottom air filter and preventing installation of a power supply.

Other Thoughts: Frankly, I don't care that one of the two arrived in one piece. One didn't, and that sets the tone for the entire experience. I have to go through the hassle of dealing with an RMA, and I have very little confidence that the replacement will be intact. Given the number of complaints about damaged units with intact outer boxes one sees in the reviews for various Antec chassis, it seems this is a common issue.

I've used Antec chassis and power supplies for years (I've built more machines than I can count, both at work and home). I can echo the sentiments found in a lot of other reviews: their quality control has gone to the dogs.

If I had to guess, I'd conclude that Antec has off-shored their manufacturing and doesn't have their own staff on site to ensure proper quality control.

Just a guess.

5 out of 5 eggsGreat Case

Pros: Since this is the first mid tower case I've used I can say it is very roomy compared to a full size. Everything fit in with room to spare. Cable management is excellent. Stock fans are quiet and keep the case cool with plenty of air flow. Its nice to know I can install additional fans if required but so far I haven't needed to. I've been buying Antec cases for over 15 years and I would highly recommend. Its not fancy looking but it does the job!!

Cons: None

5 out of 5 eggsGreat!

Pros: I love the straight face look, the quietness is great, and I like the two drives that are hidden.

Cons: Wish there wasn't a cover covering up the drives and I wish you could take out the HD bays inside there's just too much blocking up extra space, but even with them there is plenty of room but extra room never hurts.

2 out of 5 eggsTower Review

Pros: Based on the ad, box and first look this appeared to be an excellent choice!

Cons: After the package sat on a table for a week I unpackaged the tower and made the fatal discovery; the back of the case was dented right where all the peripheral cards were to be installed. Bummer!!!

Other Thoughts: Outside of box showed no sign of damage so the cause of damage had to take place at the manufacturer and got shipped either by mistake or accident. I hate to think it was done deliberately.

5 out of 5 eggsNIce case

Pros: This is a nice upgrade from my previous Antec 1030. Through the years the 1030 served me well but with the upgrades over the years and the higher thermal values that came with those it was time to upgrade.
I really like the the cable management and the level of unrestricted airflow has helped the temp of my current processor running temp drop by 15°C , 55° C to 40°C, using standard fans. I was considering a water cooler before purchasing this case.

Cons: None yet

Other Thoughts: I hope this case lasts as long as my retired 1030.

5 out of 5 eggsSilent and Easy

Pros: With the larger back panel area (almost 1") it was easy to route cables in behind the mobo and allow easy air flow. Love the dust screens. Very quit compared to may last build.

Cons: Could have used a 2nd fan on the back (or area to put water-cool rad) so I could have kept the top enclosed to make it even quieter

3 out of 5 eggsVW case for a Porsche Engine

Pros: It's such a pretty case.Lightweight and sturdy. Love the brushed aluminum, front, the rubber grommets bordering the excellent cable management. The Air filters are sufficient, sturdy, and easy to access, and there's plenty of ventilation even when the front door is closed. The side access HDD cage allows for an easy build and easy wire management. I like the the rubber grommets for liquid cooling hoses, and the radiator mount on the top is very sturdy- good features, particularly if you're looking for a Volkswagon Case with a Porsche engine

Cons: I just built a PC using a the Define R4 that I got for $5 more than this (After rebates). Compared to that case, this one felt inadequate. The p100 front door had some give to its structure, the side panels wont stay on unless the thumbscrews are inserted, the foam muffler was lightweight and peeling off the case, and the vibration dampeners were not very robust. The major flaw that was my deal breaker- and knocked off the 2nd egg was that the built-in Fans are 3 pin, and controlled with a 2-way switch hanging from a wire incise the case. The exhaust controller would fall into the video card; the intake fan controller is accessible by removing the back panel. PWM fans are not that expensive -I just bought one for $5- and it's an easy way to add value to a case. Most MOBO's can control them, and if you're buying a mobo that doesn't have the capability, and you don't want speedfan, you shouldn't spend your budget on a case this expensive.

Other Thoughts: This is a case that would be fantastic for a liquid cooled CPU or GPU, when intake/exhaust aren't so closely managed. If you're spending the kind of money needed to get the components that need liquid cooling, and the coolers for them, this case is a good way to cut cost. If you have a 4 yr old middle of the road gaming PC like mine (z77/3660K/660ti) Those features are unnecessary. I just need a good looking case because it's in my livingroom, a quiet case so that we don't have to listen to it when we're watching a movie and three fans that can be controlled by my MOBO.

4 out of 5 eggsGreat overall

Pros: Lots of open space, extremely easy cabling, solid frame.

Cons: Outside is a little substandard. The front panel/door is poor quality. I guess something had to be cut to hit this great price point.

The feet are not big enough to be able to sit it on carpet and get enough airflow for the PSU. Place a flat piece of plastic or something similar underneath it if it will be on carpet or your PSU might overheat.

I know it is a midsize case but an extra half inch in height would be nice. The space between the modo and PSU is nearly zero. It is not a problem for me since I don't need the suplimental PCI-E power, but on the EVGA z97 FTW board, that connector is at the bottom of the mobo and faces downward. If you are planning to run SLI, make sure the mobo connectors aren't like my mobo or you will be returning the mobo or case.

The real manual is missing and only available online although all the cabling is pretty well marked and self-explanitory.

Other Thoughts: This is by far the easiest case to setup I have ever had. Lots of space to screw down the mobo and the cabling is so easy.

The cons, for me, aren't enough to be too critical of the case but there are plenty of use cases where this case will not work.

5 out of 5 eggsGreat Case, Very Simple

Pros: Antec design and wiring is easy to make look pretty. Lots of room for drives and solid state friendly (no adapters needed). Case is very similar to my P280 in set up, but is much smaller.
Used this case for a build for a business here in town and I wasn't disappointed.

Cons: Don't like that it is fairly mandatory to mount the PSU with fan facing down. The screen on the bottom for filtering out dust for PSU is kinda cheap and slides around a lot.
I don't like the way the optical drive secure to chassis - think this could be done better.

Other Thoughts: Great case and would highly recommend it - especially if you are looking for a more compact case with all the options you get with high end gaming cases. No clear sides to show off the guts, if this is for a business workstation build that is nice.

5 out of 5 eggsGreat Case

Pros: This is a very good case for the money. I also got a $20 rebate. Doesn't get much better than this. This sound proofing is very effective.

Cons: None
