Small case that fits a Baby AT mobo?

I am in the middle of designing a home audio media player based on Linux software. I have been trying to find a small case that will fit the hardware I have, a FIC VA-503+ Baby AT motherboard. The board has an ATX connector, so the power supply is not an issue. Has anyone successfully fit a Baby AT board into a Micro ATX slim case like this one ? Does anyone know of a similar case that was or is made for Baby AT mobos? Thanks.
