So after attempting to add a window to my expensive Nanoxia case and screwing it up I decided to build my own case and I wanted to try to make a mac pro "trash can" type case because I like the airflow design. So I thought I would take a piece of aluminum and make a aluminum cylinder that had a diameter of 12 inches so I could fit my matx board in there. Any thoughts ? I would fit the Mobo in using a vertical stand with a tray on it.
