Question Why Silverstone, why?

Placement there allows the PSU to draw cool air from the bottom of the case and exhaust it out the back. This case will also allow fans to be placed above the I/O panel (ATX plate) to assist with airflow. Seems a fairly well thought out way to maintain a low profile case that supports full height GPUs.

I thought the psu fan sucked the heat out & exhausted it.
