Expandable for Maximum Performance

The enclosure of the P280 has customizable features for all builds to maximize your PC experience. The P280 houses nine expansion slots and space for an XL-ATX measurement motherboard (10.3 inches by 13.6 inches). The chassis also supports Standard ATX, microATX, and Mini-ITX motherboards.

In addition, the P280 supports graphics cards up to 13 inches (330 millimeters) long within a quadruple graphics card setup, so you can create what you want in one system. The P280 has three tool-less 5.25-inch drive bays--simply depress the front release lever and slide the drive out for easy access. There are also two 2.5-inch and six 3.5-inch drive bays inside the chassis.

Gaming Made Cool through Multi-Fan System

An intensive cooling network is essential for optimal performance, which is why the P280 contains two 120-millimeter top TwoCool exhaust fans, one 120-millimeter rear TwoCool exhaust fan, and four fan mounts for optional 120-millimeter internal intake fans and 120-millimeter front intake fans. The mounts are positioned strategically to keep all your gaming components operating efficiently.

The cooling system of the P280 also comes equipped with a convenient fan power hub, which allows you to connect four 3-pin fans to a single Molex for improved cable management, and additional water cooling support in the form of rear water cooling grommets, which assist in further heat management.

Multiple Filters Increase Airflow

Quick, convenient maintenance is possible with two filters in place: one PSU air intake filter and one front air intake filter. These removable, washable air filters are located behind the triple-layer front bezel, and facilitate the conservation of clean builds for optimal airflow and cooling performance.

Quiet Operation Lets You Focus on Gaming

Reduced noise levels remain a priority for a more peaceful gaming atmosphere. The Antec P280 utilizes Quiet Computing panels on the sides of the enclosure so you can pay less attention to noise and focus instead on your performance.

Accommodates Variety of Builds

An enlarged CPU cutout makes a range of motherboard designs accessible, and with convenient tool-less optical drive bays, easy-access front and bottom PSU intake air filters, and four front-panel USB ports (two USB 3.0), you get an expansive and easy-to-use enclosure that will last you for builds to come.

The P280 makes gaming the priority, rather than maintenance. Rubber grommet-lined holes are strategically placed around the chassis for convenient cable routing. There's also enough room behind the motherboard tray to accommodate 24-pin power cables.

Product Measurements and Warranty

The P280 is 20.7 by 9.1 by 22.1 inches (H x W x D) and weighs 22.3 pounds. It is backed by a manufacturer's three-year limited warranty.

Style Name: P-280 Verified Purchase
Antec has definitely provided a firm foundation for people who like to "build big" with the P280. It offers a deceptively roomy chassis with space for up to 11 drives (six of them on hot-swap trays), three built-in fans (with space for four more), and enough space for an XL-ATX motherboard with four video cards. The space on the right side of the case, under the motherboard and to the right of the drive cage, is relatively deep and easily accessible, leaving plenty of room to route cables out of sight. About the only complaint you might be able to lodge about the orgainzation of the case is that the space at the top where the two exhaust fans are is not quite deep enough to easily install some of the water cooling systems on the market (measure the size of your radiator before you buy if this applies to you.)

The construction of the case itself is solid; several touches such as double-walled construction, low-noise fans and silicone mounting grommets on the drive trays grant help keep noise down to minimum, and very little inside or outside the case looks or feels cheap. I'm using the case as a combination workstation/media server with a CoolerMaster SilentPro 600W power supply and a Zalman CPU fan and it rarely gets above whisper quiet.

That having been said, what would I change on this case?

First, the leads from the front panel to the motherboard should be at least a few inches longer; when I routed them around the right side and out the grommets, they barely reached the connectors on my Asus Sabertooth X58.

Second, the "easy connectors" for the 5.25" drives at the top of the case work great with standard drives, but drives with non-standard mounting holes can be tricky.

Disclaimer: I normally only work with high-end workstations, so I have rather high expectations.

If you want a subtle-looking case that prioritizes build quality, ease of install, silence, and expandability, then the P280 is a solid thumbs up. I have an Intel Core i7-2600k + ASUS P8Z68-V Pro/Gen3 with 2 SSD's and 4 spinning disks, a Blu-Ray burner, fan control module, and a card reader, and everything fits just fine with 2 more drive sleds to spare.

I'd like to share some subtle things that may not be immediately evident from just reading the specs.


1) Thumbscrews for the panel and the 9 PCI expansion slots
Thumbscrews for the side panel and PCI expansion slots are nice and convenient. Speaking of PCI expansion slots, the 9 expansion slots were nice, because I was able to throw in a USB2.0 and IEEE1394 rear slot adapter in the bottom two slots without sacrificing any slots on the motherboard.

2) 6 Drive sleds that support 3.5" *and* 2.5" drives
Most drive sleds only support 3.5" drives, but the P280 comes with 6 sleds that support both. While this may seem excessive today, in a few more years, when you find yourself buying more 2.5" SSD's, you'll look like a genius. Hey, those $5-$10 SSD adapters add up...

3a) Tons of space on the backside of the motherboard for cable management
Unlike other cases that claim backside cable management but only provide 1/2" of clearance, the P280 has a full inch of clearance in the back. When I was done routing all my cables, I said to myself, "There's no way the case will..." and voila, it closed *easily*. I was impressed.

Ok first off like I said in the title this is a HUGE mid-tower. It's kind of pushing the boundaries of the mid size category. Of course all this room makes this case a dream to work with. Plenty of room for everything you could want to put inside this bad boy. I ended up getting a Tuniq 120 Extreme heatsink and there was plenty of space for this monster of a cooler. I was easily able to route all connections through the numerous cable routing holes and behind the motherboard tray. The back panel closed with no problem. The front panel leads are pretty short but I was still able to get them routed through the back and down to the motherboard pins on an Asus P8Z68-V-Pro/Gen3. If the front panel pins aren't along the right edge of your board, which I have seen before, then you might have problems routing those cables through the back. Zotac GTX 580 Amp2 graphics card fit easily.

I didn't like the intended negative pressure configuration of the fans and instead went with a positive pressure config putting two 120s in front and a single 120 in the back. I sealed up the top two 120mm vents with black sound dampening foam and this baby just whispers. Love how quiet this case is compared to my old Centurion5.

Like had been mentioned in another review the top two 2.5" SSD drive mounts are very tight. I kind of forced a Crucial M4 into one of them and it fit, but it was a struggle to get in and out. I didn't like how tight that was so since all the 3.5" drive trays have mounts for 2.5" drives I just opted to put it in on of those instead. Also as had been mentioned the 5.25" mounting system works out well with optical drives but if you have a 5.25" fan controller the latching system doesn't work as it was intended.
