PSU submission...
Vibration can be a problem with some systems when the PSU is located down at the bottom of the chassis. SilverStone has managed to avoid this with some neat touches.
There's a simple plastic clip that helps to hold the PSU in place, along with two strips of rubber on the floor of the chassis. It was a pretty tight fit for our Antec PSU but it certainly worked well.
Seeing as the PSU can only be mounted one way, bottom-mounted fans are catered for in the TJ-09 with direct ventilation to the outside available between the rubber strips.
Up top the TJ-09 features the vent at the back we spoke about earlier, but in addition to this there is the option to mount two 120mm fans under the meshed area at the top. Again, simple plastic clips are there to hold them firmly in place.
