As we can see this case has the PSU mounted on the bottom of the case. If you like to run watercooling in your setup this case is also prepared for that so you can mount your radiator on the back of the case and pull the tubing through the holes that are prepared.
The rear exhaust fan is not silent but not the loudest fan that I have heard either. I suggest getting a Zalman RPM controller to lower the noise. This case does not require any tools when you mount your parts. Convenientely all the drives and cards can be installed without tools since there are thumbscrews for the addon cards and the 5.25 slots have plastic locks. You’ll find that the 3.5HDD’s have plastic rails that you stick on the drives and then simply slide them into place.
The harddrive cage has rounded corners and the rails you use to mount the drives are packed in a small white box. Below the PSU Enermax has mounted a removable dust filter so you can clean the filter to maximize airflow.
