I have a tower A2000 that a good friend gave me. It must have been made for an A2000. All the holes lined up, also it has cables for the mouse, joystick, and keyboard that run from the front to ake them to the back. You would have to have a large AT tower, maybe 3ft. and be ready to do alot of cutting on the back for the ports. I did something like it with a LPX board, into an AT tower. I cut everything south of the PSU out and used some tin to fill it in. It was a monster but it looked ok and worked
