im so sorry but the question is a little misunderstood, anyway i'll try to share my ideas,an atx casing allows atx motherboards to fit inside the case likewise for an AT to AT. the point is that any boards can be told to fit on a case just by looking at it physically, the end is that these casings has built-in switches (power switch), which basically requires the same type of boards for that switch. so you can fit an at board into an AT/X casing but you cant make it work without converting its power supply switches into its same type. most generally you'll need to replace to a new power supply to make it work same goes with other boards. goodluck!!!
