Introduction

Antec P280With their Performance and Sonata series Antec has long been one of the top manufactures of quiet chassis. Given the large emphasis we at Puget Systems place on quiet computing, it's no surprise that we heavily use Antec chassis in our product lines. In fact, just over 48% of our systems in 2011 were built using the Antec P183 V3.

The P280 is the latest addition to Antec's Performance series, but rather than being a replacement to either the P183 or P193 is more of an overhaul of both chassis. The focus on quiet operation is still present, but many of the features used to attain this focus have been completely redesigned.

Since this is a potential replacement for either the Antec P183 V3 or the Antec P193 V3 this article will be much more in depth than our normal qualification articles. We're considering replacing our best-selling chassis, so we want to be sure that we cover all the angles before making a decision. Before taking a close look at the P280, lets first take a look at the specifications for this chassis compared to the Antec P183 V3 and the Antec P193 V3:

We will be going over many of these specs in other parts of this article, but we want to point out just a few things here. First, the P280 is about an inch wider than either the P183 or P193 (if you discount the side fan on the P193) but only slightly taller. Depth wise, it is right between the P183 and P193. One of the smallest, but one of the most intriguing for us, changes is the fact that the front USB 3.0 ports finally use an internal header instead of having to be routed through to case to plug into an external port. The internal audio plug has also been changed to drop AC'97 support which is long overdue in our opinion.

The P280 has more cooling capacity than the P183 V3 or the P193 V3 which is primarily provided by the two interior fan mounts. These mounts allow for fans to be installed without having to replace a set of internal 3.5" bays like in the P183 V3 and P193 V3. The final two things to note in the P280 are that all the 3.5" bays include mounting for 2.5" drives - rather than just two of the six in the P183/P193 - and the lack of an external 3.5" bay in the P280.

Now that we have a general feel for this chassis, let's take a closer look, starting with the exterior of the chassis:

External Features

Antec P280 Front Antec P280 Bottom Antec P280 Left

Starting with the front, this chassis has a large door covering nearly the entire front from top to bottom. While a front door is a staple of the Performance series from Antec, this door has been slightly redesigned in order to accommodate some of the more common complaints about the P183 chassis. Most notably, the front ports (2 x USB 2.0, 2 x USB 3.0 and audio in/out) and power/HDD LED's have been moved to the very top of the front panel since this chassis is most often positioned on the floor next to a desk rather than on top of a desk. The power and reset switches have also been moved from behind the door and relocated onto the very top of the chassis. This means that the only reason to open the front door of the P280 is to gain access to the DVD or other 5.25" device or to clean the front filter.

The bottom of the chassis is fairly standard with just the feet and PSU intake grill. The feet are hard plastic, but have a ring of rubber on the bottom to help reduce vibration. The PSU intake features a removable filter that can be pulled out from the left side of the chassis, and is actually just below the side panels. This allows the filter to be removed for cleaning without having to open the chassis at all.

Both sides of the P280 are identical - the side panels themselves can even be switched from one side to the other. In fact, the only difference between the two sides is the removable fan filter below the side panel on the left side. There are no fan mounts in either panel, which is to be expected from a chassis with a focus on quiet operating. Like the P193 V3,  the P280 side panels are just painted a flat black and do not have the same gunmetal finish as the front like the P183 V3.

Antec P280 Top Antec P280 Rear

As mentioned earlier, the power and reset switches have been moved to the top of the chassis. Also on the top are two 120mm fan mounts which are prepopulated with Antec TwoCool fans. The top panel itself is just a single layer of sheet steel with no acoustic dampening material pre-installed. One minor gripe we have here is that the fan screws are silver instead of black.

Finally, the back of the chassis has a few subtle differences compared to the P183 V3 or P193 V3. At the top, there is a mount to hold the speed switches from four Antec TriCool or TwoCool fans, allowing them to be easily accessed from outside the chassis. Only three fan mounts are in range however, so one of those spots will always be vacant. Moving down, you can see the more than normal nine PCI slots available on this chassis. This allows the chassis to support quad-SLI (four video cards total) with the use of XL-ATX motherboards. Next to the PCI slots are two liquid cooling pass-through grommets. Lastly, at the very bottom is the standard mounting hole for the PSU. 

This chassis only supports standard power supplies, and not the Antec-branded CP series of power supply (which is slightly taller which allows a 120mm fan to be mounted to the rear of the PSU for cooling). This lack of CP-series mounting is likely due to the fact that if Antec included both the nine PCI slots for XL-ATX motherboards as well as mounting for the CP-series power supplies, this chassis would be even taller than it already is.

What seems strange to us however is that this chassis is not in Antec's Gamer or Dark Fleet series of chassis, which are focused on high-performance computing. It is in fact in the Performance series which places an emphasis on quiet operation (yes, we know how confusing it is to have the Performance series not actually focused on cooling performance, but rather quiet operation). So that begs the question: why drop support for some of the quietest power supplies we've ever used, and add support for quad-SLI which will never be quiet with standard air cooling no matter what you do? Frankly, we would rather see the standard seven PCI slots and support for CP power supplies.

Front Panel

Normally we would not devote an entire section to just the front panel of a chassis, but there are enough changes and good features here that we wanted to be sure it got the attention it deserved.

Upon opening the door, you get a view of a few of the nice features of this chassis. The door itself has a layer of sound dampening material and is double hinged - allowing it to open a full 270° and sit flat against the side panel. The door itself is also easy to remove for replacement or removal by simply pulling it off. Plastic doors such as this can sometimes end up feeling flimsy, but this door feels very solid.

Beyond the three 5.25" bays, the only thing behind the door is a large filter for the front intake. This filter is easily removed for cleaning by pressing down on the two tabs located at the top of the filter. Removing the filter also exposes the two front fan mounts which are intended to be mounted with two screws each. The power cables for these fans can be routed into the chassis via small cutouts to the right side of the mount. The only thing we would have liked to see here is matching cutouts on the left side as well so that the speed switches for Antec TriCool or TwoCool fans could be positioned in an area that is a bit easier to access.

After removing the side panels, we get more into the maintenance side of things. The front panel itself is held in with six tabs (three on either side) and two screws (one of either side). After removing the screws, the tabs can be depressed to allow the entire front to come off. The P183 and P193 used a similar design to remove the front panel, but those chassis used rails to mount the external 5.25" and 3.5" devices which would often get in the way of removing the front panel. This would often result in the need to uninstall the 5.25" devices before the front panel could be completely removed. Since the P280 does not use drive rails, there is no longer any need to uninstall the 5.25" devices before the front panel can be removed.

After removing the front panel, you gain access to the front ports (if you ever need to replace them) which are divided into two separate pieces - one for the audio ports and one for the USB ports. The USB ports are held in place with two screws, while the audio ports are held in place with a single screw. You can also see the power and reset switches which are held in place with plastic clips and a liberal amount of glue. The switches should be easy to replace if needed, although we would be advised removing any 5.25" devices first to make them easier to access.

So any news from Antec about the length of the LED/switch cables? I agree they should be much longer, especially with all the useful nooks and crannies in this case for tying away extra cable. Bit of a shame.

We still have not heard anything about the length of the cables being increased. Of course, that doesn't mean it hasn't happened, just that we have not heard of it. I wish I could be more helpful in this case, but unfortunately we don't have any new information right now.

All that is needed is a modernized 183 v4.
