Nanoxia refers to the Deep Silence 6 as a "truly gigantic HPTX case" and it really lives up to the name. Although it can easily be mistaken for a Deep Silence 1 from a simple picture, the proportions of the Deep Silence 6 are massive. Measuring 644mm tall and 655mm deep (25.4" x 25.8"), the Deep Silence 6 is certainly not going to fit into a space designed for standard ATX cases. The truly gigantic part of the Deep Silence 6 however is the weight. At 20.8 kg (45.8 lbs) completely empty, this is one very heavy case and is most certainly not fun to move...unless you're looking for an alternative to weight lifting.

Aesthetically, the design of the Deep Silence 6 is simple yet highly refined, with clean lines and smooth surfaces. We will be reviewing the standard version but Nanoxia also offers a version with a windowed left side panel, as well as a milk-white version. Although the case's frame is made out of 1mm thick SECC steel, the top and front covers of the case are made of plastic, including the doors and the "chimney". These are standard materials for almost every modern PC case, and Nanoxia doesn't break any new ground here.

Both doors are hinged on the right side with magnets holding the doors in place. There's also a layer of sound insulating material applied on the inside of the doors. The top door hides four 5.25" drive bays, two analog fan controllers, and the reset button (and anyone with children will likely appreciate the reset button not being quite so readily accessible). The two top 140mm fans come factory installed, with wiring going to the fan controllers; there's a single 3-pin connector available for a third fan as well. Next to the fan controllers, the logo of the company is embossed on the plastic. The 5.25" drive bay covers are held in place via a plastic lock on their right side and they're easily accessible from the front of the case; all of the drive covers have dust filters installed as well.

The bottom door will most likely be opened far less often than the top door, as it only covers the two 140mm intake fans. The intake is on the side of the case and so the door only needs to be opened if the filters require cleaning. Nanoxia makes the cleaning of the filters -- or even the replacement of the fans themselves -- extremely easy as each fan and filter is attached to its own smaller plastic door. By opening the door, the user can simply pull the filter out and clean it or remove the fan altogether.

The power button can be found at the top side of the plastic front panel, encircled by a green LED. Moving a little towards the rear, the hidden port cluster can be seen, which pops out if pressed. We assume that most of the time it will be left open, as these days it seems almost every user has something connected to a front USB port, yet the option to hide it entirely is certainly welcome. The port cluster offers 3.5mm headphone and microphone jacks, two USB 2.0 ports, and four USB 3.0 ports.

The rest of the top panel is covered by the active "air chimney", which can be opened/closed via the large switch on the side. Nanoxia calls this an "active chimney" because it also acts as a switch, turning off the top panel fans when closed. The switch is very tight but the whole mechanism feels very robust and the panels close firmly, even though all the parts involved are plastic. It is possible to partially open the panels, but it does not make any real sense in our opinion.

We received the windowless version of the case, yet the left side panel has an opening with a plastic cover installed. The plastic cover may be removed, allowing for the installation of two 120mm or 140mm fans. Nanoxia has fan filters preinstalled and waiting; however, cleaning those filters isn't quite as simple as cleaning the the front panel filters, as they are secured with screws between the side panel and the fans. Each time the user wants to clean these two filters, the side panel will have to be removed, then the fans, and only then can you remove and clean the filters. Both side panels also have dense sound insulation applied.

The rear of the case is not very interesting, although it is worth noting the very large ventilation openings next to the expansion card slots and the presence of four round holes for liquid cooling hoses and cables near the top of the case. The four holes are covered with rubber grommets, but if you do not need/want to have openings there at all, you may use the supplied rubber covers to completely seal some or all of the holes.

Wrapping up our external inspection, four tall, nickel-plated feet lift the Nanoxia Deep Silence 6 about two centimeters above the surface. A long air filter comes installed at the bottom of the case as well, for the PSU intake fan and for the optional bottom intake fans. To remove this filter, the user only has to pull it off from the rear of the case, though this is usually not very convenient or even possible without moving the whole case (again, not an easy task for someone my size).

    Looks like a good case. However, I'm not sure if its just me, but the titles on those graphs just look blurry to me. Also, that's the first time I've ever seen minutes of a degree so casually used in a review, I had to do a double take to make sure I was understanding it right.

    Yes, looks like it is not the optimal edge smoothing method for this combination of colors and font.

    I think Tracy made the charts manually in some other program (Excel?), and perhaps they got resized somewhere along the way. We'll try to avoid blurry images/fonts next time. :-)

    I love giant cases; easier to put things in and take things out of! That said I wish the exhaust was out the top like the TJ11, to me once I got used to it, exhausting out the top was the superior option.

    I too would like wheels but the case is already very tall; are there any low profile rollers we could put underneath (no way we'd fit regular wheels under there)
  • The PC Apologist - Thursday, February 13, 2014 - link

    Exhausting out the top is indeed the superior option since as hot air naturally rises, why not go with the flow?

    That said, the option to exhaust via the top is present. There are two lids on the top that can be raised or lowered. Once raised, it will also hot air to escape via the sides.

    Convection has next to zero effect compared to forced airflow with the fans we're talking about here. Orientation doesn't really matter. If you flip one of these cases so the back is now the top or so, you get almost exactly the same temperatures, just maybe a degree off, as shown in tests.
  • The PC Apologist - Thursday, February 13, 2014 - link

    Yes I know, the difference in temperatures is negligible. It has always upset me that the temps don't show a larger difference.
    And yet, because it should theoretically be better, isn't it enough to convince you to choose top over rear?
    All else being equal, let's go with the flow.
    But if there's a sufficient reason to choose the rear, the rising hot air thing is easily defeated.
  • lever_age - Thursday, February 13, 2014 - link

    No, you may need some special provision (extra height so extra volume overall) to allow sufficient intake from the bottom and exhaust out the top. If you do a layout with motherboard I/O facing up, having cables stick out perpendicular to the ground means more volume or some kind of messiness or contraption to guide them out horizontally. If you have exhausts on the top, dust can readily fall in when the system is not in use.

    Though depending on layout and restrictions of your living area, some arrangement using top exhaust could be nicer. It just usually doesn't seem as sensible.

    Best thing about orienting the motherboards 90 degrees rotated is that your GPUs (and in theory expansion cards) hang down from the case and this greatly reduces the stresses on the GPUs, PCIe slots, and motherboard. But simply exhausting out the top without rotating the motherboard doesn't really make much of a difference.
  • Gigaplex - Thursday, February 13, 2014 - link

    And then you get your display cables et al sticking out the top of the case rather than the back. Convenient, but ugly. The Silverstone FT03 has an interesting compromise to work around that, however the convenience factor is largely lost.
