InstallationThe internal layout of the NZXT Whisper chassis is pretty typical for a standard full-tower ATX style case except the PSU is located at the bottom. The overall installation of basic components was accomplished with ease. As you will see in the following pictures there is plenty of room to work inside the Whisper enclosure.
The power supply slides into position from inside the enclosure. It is supported by a small metal bracket shelf. Once in position the power supply is secured with four screws thru the backside panel.
Note: There is no opening in the bottom of the case underneath the power supply to bring in outside air so if you use a PSU with a bottom intake fan, be sure to mount the PSU with the fan facing up. As you can see in the photo above, the rear HDD cage partially blocks airflow to the PSU, however the easy fix is to just remove the rear HDD cage. Another potential problem with locating the PSU at the bottom of a full-tower enclosure is that the PSU cables need to be quite long to reach all the way up into the motherboard area.
Exposed Drive Bays – Optical Drives
Before a 5.25” drive or bay device can be mounted a black plastic bay cover must be removed from inside the front bezel. Once that is accomplished you just slide the drive in from the front and lock the drive into position with the tool-less side latch. In practice this mounting arrangement proved to be convenient but not very robust. It’s nice for a quick install but the tried-and-true method of using screws to mount the drive is a lot more secure.
The Whisper comes with one 3.5” bay adapter mounted in the upper drive bay, which can be removed if not needed.
Internal Hard Disc Drives
The lower section of the Whisper chassis contains three HDD cages (any one can be removed if desired). The front cage can hold up to five 3.5” HDDs while the two back cages can hold up to two HDDs each. Hard Disc Drives mount in metal trays with rubber grommets to help minimize vibration noise. This is a good strategy but unfortunately you wind up with a metal HDD tray sitting in a metal slot, which leaves the potential for vibration noise. In practice though, I found the HDD trays fit into their corresponding slots rather tightly.
I installed a full size ATX motherboard (Asus P5N32-SLI Deluxe) and dual video cards into the NZXT Whisper enclosure without issues. The chassis uses threaded standoffs for mounting points and everything lined up and fit perfectly. As you can see in the photos there is a good bit of room around the motherboard area to work and connect cables.
