Depending on how old, you are better off getting a new case ($35 or so) to fit the new motherboard. &nbsp;Case and board together should run $150 or so depending on board. &nbsp;That way you can upgrade to an ATX board with all the goodies. &nbsp;If you don't want a new case, you are stuck with boards that fit. &nbsp;If it is a tower, an AT or Baby AT will probably fit. &nbsp;If it is a desktop, what will fit depends entirely on the case and manufacturer of the original machine.
