A Detailed Look at the Inside
Removing the left side panel provides a good view inside the Whisper full-tower enclosure. There are seven 5.25” drive bays located down the front of the Whisper enclosure. One of the upper bays comes fitted with a 3.5” drive adapter. As you can see the Whisper enclosure is divided into two section: the upper section houses the motherboard and ODDs while the lower section houses the PSU and HDDs. Keep in mind this division also separates the airflow thru the case; more on this later.
Looking up into the motherboard area you can see the single 120mm exhaust fan on the rear panel. There are a total of 7 expansion slots and each slot cover is held in place with a dedicated machine screw (no tool-less quick releases here). The motherboard tray uses brass standoffs and includes mounting holes for E-ATX, ATX, and M-ATX form factors. The Whisper enclosure is advertised as having noise dampening foam pads on the inside of the top panel but as you can see our review sample does not.
The lower section of the Whisper enclosure contains nine 3.5” HDD bays. Each bay is fitted with a removable tray that uses rubber grommets to mount individual HDDs for sound and vibration isolation. 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.
The power supply is designed to mount in the bottom of the chassis and is supported by a small shelf bracket. This location helps keep the case’s center of gravity low.
