Any Micro ATX case will work. I myself have been searching for some time to find a case that looks nice for a AmigaOS 4.x machine, I found a flex-atx case on ebay I would love but they only ship within the states 
So im still trying to find a micro-atx case I like.
Here is the Flex-ATX case I liked:
(ps I would gladly pay someone in the states to buy/ship it to me with payment in advance some day) 
I am using
http://www.myus.com for stuff like that, try it, they are good and not expensive.. get a free account, and then you get a forwarding US address you provide to the US seller when ordering at stores that don't ship outside US.. hope that helps.
