Corsair is going to release a new mid-tower series of computer cases, named Carbide, with two models. The 400R is scheduled to arrive on the market on 08/31/2011 at USD 100, and the 500R is scheduled to arrive on the market on 09/30/2011. They have features not usually found on mid-tower cases such as eight expansion slots. Let’s see if the 400R will be a good buy.

The left panel of the 400R has a mesh supporting two 120 mm or 140 mm fans.

[nextpage title=”The Front Panel”]

The front panel of the Corsair Carbide Series 400R has four external 5.25” bays, all using meshed covers with air filters.

The buttons and connectors of the case are located on the front panel. The 400R comes with two USB 3.0 ports, one FireWire port, and the traditional audio jacks. The USB 3.0 ports use an internal connector, so you won’t need to connect them to the motherboard external USB 3.0 ports. If your motherboard doesn’t have an internal USB 3.0 connector, you can install the USB 3.0 ports to a USB 2.0 header, thanks to the adapter that comes with the product.

At the bottom part of the front panel, the 400R comes with two 120 mm sleeve bearing fans, and there is a washable air filter in front of them. These fans glow in white, and you can turn their LEDs off by pressing a button located on the top part of the front panel. See Figure 5. Unfortunately, the manufacturer doesn’t publish the technical specifications for these fans, and the original manufacturer sticker was replaced by a sticker that has only the Corsair logo. These fans are connected to a standard peripheral power connector, so you can’t monitor their speed.

[nextpage title=”The Top, Bottom, and Rear Panels”]

The top panel of the 400R can be seen in Figure 7. It has a mesh, supporting the installation of two 120 mm or 140 mm fans.

The bottom panel has a big, removable air filter, covering the meshes available for the power supply fan and for an optional fan.

The rear panel and the interior of the 400R are painted black.

One of the highlights of the Corsair Carbide Series 400R is the presence of eight expansion slots. (Usually, cases have seven.) This allows you to install three or four video cards in your system, depending on your motherboard. The slot covers are vented.

There are four holes for hoses of liquid cooling solutions, all with rubber covers.

The 400R comes with a 120 mm fan installed on its rear panel, but no technical specifications for this fan are provided. This fan uses a three-pin power connector, so you must install it on your motherboard, allowing you to monitor its speed. You can replace this 120 mm with a 140 mm model, if you want.

Let’s now take a look inside the Corsair Carbide Series 400R.[nextpage title=”Inside the Corsair Carbide Series 400R”]

Both panels are attached to the chassis using black thumbscrews. These thumbscrews stay permanently attached to the side panels, so there is no way you can lose them. The motherboard tray has a huge hole for you to access the backplate of the CPU cooler without having to remove the motherboard from the case, several holes protected with rubber covers for you to route cables behind it, and a few metallic clips for you to fasten cables using cable ties.

In Figure 13, you have another overall look inside the case. Expansion cards are fastened using black thumbscrews. The 400R supports video cards up to 12.4” (316 mm) long.

The power supply is installed at the bottom of the case. Note that it can be installed with either its bottom fan facing up or facing down, so you can decide if you want the fan of your power supply pulling air from inside the case or from outside of it.

If you in
stall a power supply up to 6.9” (175 mm) deep, you can install a 120 mm or 140 mm fan on the bottom panel. With a power supply up to 7.3” (185 mm) deep, you still can install a 120 mm fan. But if you have a power supply deeper than that, you won’t be able to install a fan on the bottom panel.

As shown before, the bottom panel has an air filter for the power supply fan and for this optional fan.

[nextpage title=”The Disk Drive Bays”]

The Corsair Carbide Series 400R has four 5.25” external bays and six 3.5”/2.5” internal bays. All bays use tool-less installation mechanisms, except when you have 2.5” devices.

Each 3.5”/2.5” bay is actually a small drawer, with rubber rings around its pegs to absorb vibrations and, thus, reduce noise.
