Nothing on that case that says who it was made, looks to just be a generic mid tower case.
That little 80 mm fan isn't much help. Would get better airflow out the back if you could replace it with a bigger fan, which from the looks of it would be a 92 mm. A bigger fan will move more air and be a bit quieter as well. Also if possible a fan in the front would help with getting cool air in. Maybe even look to mounting a fan over the grill on the side panel to help with cooling the video card, not sure if a 120 mm would fit or not but a 92 mm would help, or if you replace the 80 mm in the back and use it on the side panel.
Another thing that will help with airflow and better cooling is to clean up the wiring as best you can to stop them from interfering with the airflow. You don't have to go this far, Looking for Cable management tips.
but tucking them out of the way does help.
