The two side panels of the Nanoxia Deep Silence 8 Pro are covered in a heavy-duty sound dampening material, which adds to the hefty overall weight of the chassis.
On the inside, it looks as though Nanoxia employed a good OEM, as we have seen this layout before. The shroud is made out of steel and holds the mounting bracket for a vertical GPU riser cable. That said, you will have to buy the cable separately.
On the opposite side are the openings for the HDD cages in the main area of the chassis and well-placed zip-tie hooks for you to keep things as clean as possible. This includes those 4-holed humps we have seen a few times in the past. While I am a fan of those, they don't lend themselves too well to larger and thus sturdier zip ties. You will find two separate, metal 2.5" HDD trays underneath the large cutout for the CPU cooler backplate. Talking about cutouts, the Deep Silence 8 Pro lacks grommets, which is usually an annoyance, but since this case does not come with a side panel, that is just fine.
You may install up to eight 3.5" drives right out of the box, which is rather unusual. This further cements the enclosure's focus on workstation users. Two drives may be placed underneath the shroud, in their own style of trays, while the six above the metal separator can be removed two at a time. By doing so, you reveal the two fans from the inside and the fact that you may install a radiator of up to 360 mm here by sacrificing the hard drive cages. That said, doing so essentially goes against one of the main purposes of this case, at which point you should really look at the many other better-suited options for your use case out there.
In the top is the 5.25" drive bay, which in itself is also rather rare these days. You may install a drive with the use of traditional screws if you like.
In the rear, the PSU bay comes with two thin foam spacers on which your power supply will rest. There is plenty of room for larger units, so you should have no issues installing a high-end unit. The eight expansion slots use traditional screws to hold the covers in place, so assembly is not tool-less. You will also have to remove the bracket if you don't want to use it. Considering it is useless unless you spend more money, shipping it as part of the accessories or even just with a riser cable itself would have been better.
Looking at the solid ceiling, you will find another layer of sound dampening nicely fitted into the space.
All the cables within the Nanoxia Deep Silence 8 Pro are sleeved black and of the classic variety. They are all actually rather long, so you have to play around during assembly to route them all cleanly.
