Installation of Components

Power Supply

The Suppressor F31 case is designed to mount a standard ATX power supply at the bottom. The PSU sits on four rubber pads. As a test, we installed a typical 750W PSU into the case.

The power supply dropped easily into position and is secured with four screws on the backside panel.  Installing a typical (160mm deep) PSU will leave you with 5.5” of space between the PSU and HDD cage for cables. The power supply can be mounted either with the fan up to pull air out of the case or with the fan down. The dust filter covered opening on the bottom of the case allows outside air into the PSU when the PSU is mounted with its intake fan down.

Motherboards

The Suppressor F31 case is designed to mount three different sizes of motherboards including ATX, Micro-ATX and Mini-ITX form factors. We installed both a Mini-ITX and a standard ATX motherboard into the case and in both cases everything lined up perfectly. And there is a large cutout behind the CPU socket area to facilitate installing/changing CPU coolers.

VGA Adapters

We also installed several VGA adapters to test the fit and once again everything lined up as expected. The expansion card slots all use thumb screws and the Suppressor case will support cards up to 278mm (10.9”) long or up to 420mm (16.5”) long with the HDD cage removed.

External 5.25” Optical Drive

The Suppressor F31 has two external 5.25” drive bays located at the top of the front panel, which are hidden behind the front door. Our 5.25” Blu-ray burner slid easily into position and locked in place without tools as advertised. Drives can also be secured with machine screws if desired.

Internal Hard Disc Drives

The internal 3.5” HDD cage is designed to mount up to three 3.5” HDDs or 2.5” SSDs. The cage contains three plastic drive trays, which are designed to hold either a 3.5” HDD (no tools required) or a 2.5” SSD (mounted with four machine screws).

Alternately, there are three mounting locations on the right side behind the mobo tray. The 3.5” drive trays clip into position without tools. Unfortunately you can’t use both the drive cage and the locations behind the mobo tray; they both require using the drive trays, so you are limited to three internal drives.

If you use the drive mounting locations behind the mobo tray, the internal 3.5” drive cage can be removed to free up space for wiring, increased airflow and a neat look.
