Hi 22warrior, and Welcome to the AMD Forum!
It's hard to say from the info supplied on your link.
If your back panel has the PS/2 mouse and Keyboard connectors side-by-side, and both the same size/style of connector, then your motherboard is the modern ATX style.
If the Keyboard connector is larger, (1/2 ~3/4" in dia.), and off by itself, then you need the older AT style of case.
Best bet for one of those is to check the 'curb-sale specials' in your neighbourhood, on garbage day.
It's amazing what some people throw away!
