The Silent Base 600 case is designed to mount a standard ATX power supply at the bottom. As a test, we installed a Be Quiet! Dark Power PRO 1000W PSU into the Silent Base 600 chassis. The power supply dropped easily into position and is secured with four thumb-screws on the backside panel. Installing a typical (160mm deep) PSU will leave you with 5~6” 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.
The Silent Base 600 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.

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 Silent Base case will support cards up to 294mm (11.6”) long or up to 413mm (16.3”) long with the HDD cage removed.
