Experience: 3 Months


Dust Free
Sleek Looks
Lots of room
I have owned these bad boys for a long time now.
They look good, professional, clean, sleek. Kind of like a batman's computer.
Wonderful to work with as well. No sharp edges like the cheap cases I used to purchase.
Lots of room inside the case to get the job done as well. I personally use it for an all around PC.
Quiet PC even with the video card fan on full blast. I wish I bought my sister the same PC. Her computer makes a lot of noise. If you don't like a lot of noise, then you must get a silent PC and not look at the cost. Peace of mind is worth a lot more. Believe me.

Experience: 6 Months


- quality material
- quiet, good airflow
- larger than it looks
Got the white version of this; front usb ports are nice and cable management is quite good. Harddrive bays are very easy to operate. The power button is kinda placed in an awkward position though. Very heavy case, but good noise insulation.

Experience: 1 Years


Quiet and easy to use
This is a very good case, it's quiet, lot of room for expansion.

Experience: 7 Days


Lots of room for cables and large video cards. No need to cram stuff. unique way of mounting and connecting hard d rives...and it works. Very quiet fans.
none that are really important. Yes i knew before ordering that a door has to be opened to access the optical drives.
This case is almost perfect as it is.

Experience: 5 Months


Lots of space for drives, designed well for heat-sink attachment, plenty of cooling options.
Wrong size screws for attaching drives. They fit very loosely, unlike the screws for the Antec P180 (which I also own).
Case was fine, but I was not satisfied with Antec support. They sent me a replacement kit labeled P280 (despite the fact that I had given them the exact length of the proper screws), then told me that it was working as designed. If I knew that would be their response, I wouldn't have bothered.
Anybody want two sets of wrong-sized screws?

Experience: 6 Months


Quiet, plenty of room for even the biggest of mother boards along with plenty of 3.5" bays.
I bought this case to house my HTPC build.
I wanted a quiet case.. for obvious reasons.. when you are watching a movie and don't have your surround sound on.. you still want to hear the movie and not the sound of fans.. this does the job.
The three included fans are quiet and I even added two more noctua 120mm fans still quite and there is still room for two more fans.
Space is generous with the ability to add up to six 3.5 HDD's or six ssd's plus it has two dedicated slots for ssd's plus space for you 5.25" drives.
Design is perfect for the understated look. It may be big.. but it's not goddy looking. When the system is on.. the 2 little blue LED lights on the front are barely noticeable and the front panel door that hides the DVD/BLU RAY compartments is the perfect touch.
I would recommend this case to anyone not looking for all the flash most gaming machines have but still offers the room for all the mother boards and graphic cards out today.
If you are looking for a bit of flash they do offer this same case with a side panel window.

Experience: 3 Months


-Big enough for anything
-cable management
-simple design
-dust filters
-Takes up a lot of space
-no option for 140mm fan
-side panels sorta flimsy
-stock fans are loud
While I am quite happy with the case and the boxing day deal of 79.99 got me to finally build my new gaming comp, the case is really big. It may hold everything, but it takes up a large part of my desk and the fact that the 3 stock fans are quite loud even when set to low. Cable management and space is quite nice, but just make sure your psu cables are long enough to take advantage of this. My cheap antec 650w cant route through the back and plug in so that was a bummer. Fan filters were a nice last touch, but I would recommend buying new fans if you want to have a silent case.

Experience: 3 Weeks


Lots of room for cables
Good airflow
Hard drive screws too long
Back of case is perforated
Bought this case to replace my aging P182.

The airflow is much better, the door doesn't restrict airflow like the P182 did and the air filter is larger plus easy to remove and clean. There's lots of room for running cables with tie down spots everywhere.

The included TwoCool fans are actually decent sounding running on low speed. Because of all the ventilation holes in the rear I swapped the fans for Scythe Slipstreams, 500rpm for the exhaust and 1200 rpm for the front intake to help balance the case pressure and keep dust out.

I'm not a fan of the plastic drive trays, metal would be preferable here. Also the hard drive mounting screws are about 2~3mm too long for my WD hard drives. I had to steal the screws from my P182 which have the correct length to seat against the silicone grommets. A couple of 12mm diameter washers would also work to take up the extra length.

Experience: 2 Months


-Build Quality
-Simple Elegant design
-Negative air pressure
-The drive cage plastic isn't as sturdy as steel ones from Fractal
I've been very happy with this case so far. Lots of space for fans, includes 3 exhaust fans. This leads to my complaint, there's a great front filter; however, the negative air pressure in the case leads to dust getting in from every vent, even the non-filtered ones. The other complaint is that the hard drive mounts are plastic and not as durable as the steel design from Fractal. Overall, great case, not the quietest case out there, but does a good job to prevent vibration noise, and cooling is great as long as you think about fan speed and placement.

Experience: 21 Days


Well built. Good looking. Plenty of space. Quiet.
I bought this to replace an aging Antec Sonata II. Some of the features I really like include:

Quiet - this case is very quiet, much quieter than the case it replaced. It just makes computing that much more enjoyable.

Great looks.

Well made.

Good cable management, it's a treat to be able to route cables out of site, and dress those that are visible.

Plenty of circulation with the three included fans.

Easy access to power and reset switches.

A fabulous deal at the sale price of $70.

Comment: Antec's engineers made an awful lot of changes when they designed the P280, and it's fantastic to see the kind of innovation here that I used to expect fairly regularly from them. They took a lot of the best ideas from existing designs and applied some of their own, and the result is an encl

Comment: Antec has shown once again with the P280 that it is still possible to engineer a unique chassis at an excellent price point without having to resort to generic tooling or crazy designs.

Comment: The Antec P280 Super Mid Tower chassis proves that mixing a bit of the old with a lot of the new delivers a chassis worthy of classification of "Super"!

Comment: Antec set out to update  the Performance One series based on customer feedback, but keep the style that is the Performance One series. They did just that, and released a nice case in the process.
