Inside the Corsair Carbide Series 400R Mid Tower Case
Opening the side panels, I ran into a neat feature where Corsair has "secured" the thumbscrews to the panel. This way when they are out of the case, they don't ever leave the panel so you will always know where it is when you go to replace the doors.
With the panels off the 400R we get our first peek inside of it. The paper work is all sealed in the baggies at the bottom while the hardware is in the white box in the hard drive tray. Just taking that extra bit of care, Corsair also wrapped the USB 3.0 connection, FP Audio connection and the IEEE-1394 all get wrapped in some extra padding.
With all the extras out of the way and the wiring tucked behind the motherboard tray you can now get a much better look at things before I get to specifics on each section.
The four 5.25" bays offer these springy clips to hold the drives in pretty well on their own. Once the cover is removed you just slide the drive in and it will lock into place. To release it, you just slide the "push" button to the front of the chassis and the clip rises to release the drive.
The six trays for the 3.5" drives also have holes in the bottom of the tray to accommodate any 2.5" hard drive as well. The trays are made of thin plastic that allows you to flex them over a drive easily, but leaves them "limp" installed in the case empty. You can also add two 120mm fans to the inside of the drive rack to blow at the expansion cards.
The floor of the chassis offers four rubber pads to support the PSU over the left fan hole. The right hole is for any optional fan you choose in 120mm or 140mm sizes.
The motherboard tray offers a large access hole for coolers, five wire management holes, and the risers are pre-installed for an ATX motherboard with extra holes to support Micro-ATX boards too.
The back of the chassis has the third installed fan at the top above the eight expansion slots. To remove the covers there is a cut out in the back edge of the case to get a straight angle of attack on those thumbscrews.
Behind the tray there doesn't seem to be a lot of room for the wiring, but don't forget, the panel gives you all the room you need. Already connected, to the left are the front fans that are wired to the front I/O for the lighting switch and get powered with a 4-pin Molex connection. The other 3-pin wire hanging on the right is for the rear fan.
I really like that all the wiring remained black and this wasn't a cost cutting measure lost with Corsair. The IEEE-1394, HD Audio, USB 3.0 and all the motherboard connections are as black as they can be for a good looking finished result.
