Prominent 9 Premium Case With Noise Absorption Foam
(3 reviews)

Nexus Prominent 9 Premium Case With Noise Absorption Foam

- Replaced by the Nexus Prominent R Premium Case With Noise Absorption Foam

With acoustic material, Real Silent fans, tool-less installation and removable HDD cages, the Nexus Prominent 9 is a real contender for your next PC case.

The Nexus Prominent 9 case is a great choice for a ultra-quiet computer. Thanks to its tool-less installation features, it is a breeze to install components.

The sleek professional look and materials make the case fit in anywhere. A black mesh front and aluminium edges give the Prominent 9 a distinguished look.


  1. Tool-less installation
  2. Supplied with two Real Silent fans
  3. Elegant interior and exterior
  4. Acoustically lined side panels
  5. Mesh front for better airflow

Nexus has fitted the case with their excellent case fans. There is a 140mm fan fitted on the ceiling and a 120mm fan fitted as a front intake fan.

They have also used isolating padding where the PSU is placed to prevent any resonance.

At the bottom of the case you will find ventilation holes (and space for a fan) for air-intake.The thick rubber feet keep these holes elevated from the floor to aid airflow and eliminate resonance.

Noise absorption

The Nexus Prominent cases are fitted with noise absorption material which is a premium dense foam/rubber-like material with great noise-reducing characteristics. This material is fitted to both side panels, i.e a flat layer on the panel behind the motherboard and a wave-form foam layer on the other panel. These materials help in reducing any airborne noise.

Tool-less installation

Virtually all components can be mounted inside the case without any tools. The PCI slots and Optical drives are fixed with tool-less solutions.

Removable HDD-trays with vibration absorbers

The hard disks are fitted in removable trays to make installation easy and secure. The hard disks are fixed inside the trays with screws and rubber grommets to absorb noise and vibrations.

Some cable guides have also been installed to neatly install the cables for a cleaner look in the system.


Nexus have fixed some really great padding on the areas where normally the PSU would make contact with the chassis.

They have also attached some really great patches on the bottom of the case and a really great anti-vibration gasket PSU opening at the back of the case. These 'bumpers' are made from soft foam/rubber-like material and are designed to absorb vibrations caused by the PSU and prevent any resonance being transmitted onto the chassis.

Customer Reviews

An Excellent case


I had no problems with this case apart from the fact that the Gigabyte Z68X-UD3H-B3 motherboard presents its SATA connectors parallel to the board rather than facing upwards and this meant it was a bit of a fiddle to get the drive cables inserted when you can't see the opening of the connector.

I would also recommend fixing the CPU cooler to the board before screwing it to the case as one of the push pins holding the cooler to the board is almost under the cooler and the case fan gets in the way if you try and insert it when the board is in the case.

The only other thing worth noting is that I got a fair bit of hum/vibration from the PSU (NX-Value-430) but this was largely removed by fitting soft anti-vib stick on acoustifeet. The only thing is that the feet have to fit to the case feet which don't provide a fully flat surface for them.

Very happy with this case


Minor quibbles - you need a screwdriver to install a hard drive into one of those drive cages, so tool-free installation of the cage into the case doesn't seem much of a gain. I'd prefer more of the screws to hold the cages securely in place and ensure no rattling (there isn't any rattling, but...). I'm not convinced the noise-absorbing foam makes a lot of difference, since there's a direct route for noise from CPU cooler through the vents at the top of the case - though the overall quality of the case *does* make a difference. Finally, the way those 5.25 bay covers were rattling around in the box, I'm amazed nothing was damaged in shipping.

Despite the quibbles, easily the best case I've ever owned.

Looks much nicer in real life than it does in its photo!


I use Edius/HDStorm for video editing and, as I move to high definition video, I wanted a quiet case with room for at least 5 hard drives - RAID 0 is recommended for HD video data, so I decided to install RAID 10 for extra security. Yesterday I rebuilt my machine in its new Prominent 9 case and added the 4 RAID discs.

Everything went together very easily and there is plenty of room inside to work. Being able to slide the two HD cages in from the front, having fitted the HD's in them, made things SO much easier. The ability to unclip/refit the front grills quickly is a good idea and makes the case versatile. I now have a very quiet video editing PC that looks smart. The fans are very quiet and the acoustic padding seems to work well.

It might appear from the photo that there is no power or HDD activity light - in fact these are neatly incorporated into the power and reset buttons respectively. Only criticism is that there are one or two rough edges on some of the internal cut-outs.
