Probably one of the few realistic options for small form factor cases with tight PSU spacing. The stock Wraith cooler for the Ryzen 7 2700 is big enough to fight the PSU for airflow. As others have pointed out, the ribs hang from the mounting screws on one side. Purchase a Philips #1 long precision screwdriver BEFORE you begin the installation. Anything else will drive you nuts if you try to use it without chewing on the ribs or the head of the screw. It seems like a 5mm offset to one side would make a big difference in usability.
