5 out of 5 eggsCan't think of a real flaw

Pros: Plenty of room, very easy to work with; padded, slide-out brackets and cable holders abundant. Muffles noise just fine. Room/cable management contributes to decent airflow.

Cons: Might be a little larger than whatever size you imagine it is.

Other Thoughts: Have 1 at home, 2 at work, easiest to work with case I've had so far.

5 out of 5 eggsGreat Case...Big

Pros: Layout is great, which makes working inside it easier. Cable management is wonderful, keeping the cables away from the parts, making it, again, easier to work around inside. Easy to remove dust filters.

Cons:! May need longer cables to make all the connections, but worth it.

Other Thoughts: Definitely won't fit into a small or standard sized desk. Had to remove the door and the top drawer of the desk to make it fit.

Added Antec's TrueQuiet fans for more airflow, ventilation, and quieter fans.

Great case and highly recommend!

5 out of 5 eggsA quiet, clean and simple looking case!

Pros: The P280 is QUIET compared to my previous case which was the Antec Three Hundred. The 1TB WD Caviar Black emits a lot of noise to the case. With the anti-vibration mounts for the mechanical drives make a world of difference. The sound dampening materials keeps the internal noise inside also makes the overall feel of the case solid.

The sleek looks makes the P280 classy, especially with the front brushed metal door. The door hides the 5.25" drive bays and the two front 120mm intake fans. The door also leaves plenty of space on the sides and bottom for the front intake fans.

This case includes lots of cable management holes with plenty of room behind the motherboard tray. Useful if you have a non-modular Power Supply. The cable management holes also have rubber grommets to protect the cables from tearing on the metal edges. The black interior is a bonus.

Cleaning Dust filters is a breeze as the front dust filter can be easily removed without having to remove the front cover on the case. Also the PSU dust-filter on the bottom of the case can be removed from the outside without having to remove the side panel.

Cons: My only complaint I have with the P280 is lack of ventilation.

While the rear ventilation holes are great, the two intake fans aren't good enough to create positive air-pressure inside the case as there are three exhaust fans to fight against. I have a reference Nvidia GTX 660 Ti graphics card exhausting hot air to the back of the case. This maybe a problem as that hot hair from the graphics card gets sucked back in the case through the rear ventilation holes causing the graphics card to heat up at unpleasant temperatures.

My solution was to preposition the top two exhaust fans as intake fans to create positive pressure inside the case pushing that air out through the rear ventilation holes. Although it isn't recommended to use top fans as intake fans as heat rises, it solved my major heat issue happening at the back of this case.

Other Thoughts: I would highly recommend purchasing two quality intake fans as this cause only comes with three exhaust fans.

The P280 has a simple design, removable dust filters with easy access, awesome cable management, black interior and is noticeably quieter compared to other standard cases. The only con is lack of ventilation.

3 out of 5 eggsCheap fans

Pros: Great price for such a spacious tower. Definitely does not lack the airflow capability.

Cons: cheap fans.
I bought two of these, and out of 6 total fans, three of them have started making loose bearing style noises and I replaced them with cheapo cooler master fans that have yet to ever fail me.

Other Thoughts: If I didn't need these amount of PCI slots for the machines I built, I would of went with a Fractal Design Define R4 for a similar price. They are quieter too.

3 out of 5 eggsA Little Disappointed Coming From the P183.

Pros: Great design. Very spacious. Lots of place for fans, HDDs, etc. Great cable management. Doesn't have any useless rice/junk features. I didn't want a case that has stupid blue LED lights or a huge side panel window; this case is sleek and mature looking. Power/reset button on top is a welcome change from P183.

Cons: I guess I'm a little disappointed with this product. For starters, the case doesn't sit flat - the back left rubber foot is off by a little bit and the case will wobble if you press it. It seems like the bottom of the case got bent to cause this.

My previous build used an Antec P183. I guess I am a little spoiled by that; I think that is the best case hands down. The build quality is noticeably cheaper on this case. Plastic is used for parts that were metal in the P183, such as the HDD sleds. The front door magnet is also too weak in my opinion. Don't get me wrong, this is a great case, I was just expecting another P183.

Don't get me wrong, I like the case, the quality is noticeably lower than previous Performance One series cases.

Other Thoughts: As I mentioned, the back left foot is misaligned, so the case does not sit flat. I would return this case and try and get a new one, but that is too much of a hassle. I guess I loved my P183 too much and expected this to be better, but it simply is not.

Case is also quite big, that can be either a pro or a con.

5 out of 5 eggsAwesome!

Pros: This case keeps pet hair out very well!
The main reason I bought this case was for the space I needed inside to mount drives and gpus. Not only does it keep my PC quiet but I was surprised at how well it kept my dogs fur out.

Cons: I've owned it for more than a year now and I still can't find a con.

2 out of 5 eggsthanks to Antec, I bought my first Fractal case.

Pros: The case is just as you would expect from Antec. There is a lot of flexibility with the case, great design for ample cooling, and the case doesn’t scream I am 12 yrs old and swayed by shiny lights.
Features I liked:
• Plenty of space to suit any needs

• 2 locations to put in a 240 mm cpu cooler.

• Case absorbs the sounds of the fans well

• Plenty of room for a large video card, in my case 3 slot 12”, with plenty of room for my CPU cooler

• Fit and finish is done well. I like that the front door can go all the way back and eliminates the risk of the door getting broken.

• Ample drive storage

• Lots of ways to manage cables for a clean and tidy look.

Cons: There are two major flaws with this box, the first is the hard drive screws, the second is the fan power hub.

The screws are narrow and too long to safely secure any hard drive to the cradle. The gap between the screw and the silicon grommet is so wide that I can easily put in two washers to fill the void. However, even if I do that the drives are not secure because there is another gap where the screw is inserted into the grommet. The basically provides a shaky, wobbly place for your drives to be.

I have contacted Antec and requested replacement screws from their SOLO II case which has only a marginally smaller grommet. Their response is “the screws are longer because this will create a gap between the rail and the hard drive and the screws are not meant to be tightened all the way” and “vibration from the hard drive is absorbed by the screws and the silicon grommets muffles the vibration”

Well, that would mean that the drives are suppose to bounce around but you wont here it because the silicon will absorb that and that they failed on the SOLO II deisgn. Sorry Antec, either you failed on the SOLO II or you failed on the P280. You cant change your stand on proper mounting and expect the customer to nod and agree blindly.

I have eight 4tb drives and not willing to risk them being damaged due to 1 dollars worth of screws. Do to the lack of support from Antec regarding the included drive screws, I have bought my first non-Antec case in 5 years. I build pcs for a living and have exclusively used Antec for the quality, finishes, quietness, and tidy look.

That has changed over of a bad design that is compounded by the lack of support from their online team. It is an insult to the customers to tell them we made a loose screw so you cant over tighten it even though we never did this on any other cases.

The message they send is that their customers are so dumb that they have to prevent them from doing hard during a build; well antec, news to you, they can still over tighten the screws and break them off into the HD.

The second issue is with the fan hum. It interferes with the use of a 240 mm cpu cooler. In addition, the provides slots for High/Low buttons are useless as it would only work for fans that are close to the hum. It is also in the rear of the case which is not convenient to adjust.

Lastly, it uses a molex for power of which for me would require that I add an additional cable to the power supply, of which I don’t want. It is my opinion that getting with the new technology and using a sata power source would be more advantageous. But that is just speaking for my own builds, others may differ.

Other Thoughts: I like the P280 case but as you have read dont like being treated like an idiot over screws that are c_ra_p. if you opt to purchase the case my advice is to order the SOLO II HD screws at 800-222-6832. i dont like have to buy screws when i already bough them.

As such i would advise you take a close look at the Fractal Design Define R4. I bought this one to migrate my pc too. it is very similarly equipt, however it has WAY more space and ability to cool the components with 140 mm fans instead of the 120mm.

I paid $150 for my P280, and $90 for the R4. IMO go with the R4. you will get more for your money and not have to sacrifice anything in the process.

bye bye, antec, hello fractal.

4 out of 5 eggsGood case, kind of big

Pros: Love the cable management and air filters. Good airflow.

Cons: Is bigger than the picture looks. Installing the optical drive was interesting there were metal punch-outs blocking the optical bay that stumped me for a second. Apparently you just have to twist them until they pop out. Not sure why they are there in the first place. Instruction gloss over their removal.

Other Thoughts: Good case, kind of big and overkill for me but I do overall like it. Not a LAN party kind of case. Just keep it at home

5 out of 5 eggsLarge Case, But Wonderful

Pros: Large interior, thumb screws just about everywhere, wiring channels, SSD and USB 3 friendly, lots of quiet fans, not a big glowing box (not a fan of tons of lights)

Cons: The 5.25 bay was a pain for mounting my DVD drive, was worried about breaking the sliding hold mechanism cos it is flimsy feeling tin and I had to push REALLY hard to get the drive to go in as the teeth for that part was catching the mount holes prematurely. I got it in, but like I said - was worried about that busting.
I also was a bit disappointed that no front fans came with it, however it did look like you could mount them.

Other Thoughts: Not sure what the complaint about a plastic door was cos I too got a metal doors (maybe this is a different revision?).
Also if you don't want to run a molex up top to run all 3 fans YOU CAN pull the wires off the board and just use the 3 pin header - you may also have to turn one of the top fans 180 degrees to make the cable run all the way down to the header on the board (I had to with my M4N98TD).
This case is VERY quiet and I am super happy with it going from a P180 to this. I also like how they changed the dust screen on the front - kudos to that, great design. the channels are wide and I got a lot of rails (24pin power, 8 pin CPU, and both of my SLI PCIE power) through one of the channels.
Highly recommended!

5 out of 5 eggsOne honking big case

Pros: Room and more room and more to spare. I had a P180 and really liked it. But this case blows it away. Especially with the cable routing. Also much to my surprise it is quieter than the P180. Be warned is huge.

Cons: None other than the size. But then again that's why I bought it.
