Theres nothing behind the fan and I don't realy want to block up any airflow. This is the 3rd wooden case ive put a pc into and believe me it doesn't get as hot as what its made out to be. Its only a P3 733mhz and after 6 hours of use it wasn't even luke warm. Its not a air tight seal around the box so hot air can escape. Another feature which I looked at was theres a spare speaker grill thats not in use at the top, so that acts as a vent. Will keep you updated.
