I've got the following two mini-ITX cases:
Casetronic C134 mini-ITX case
VoomPC-2 Automotive Mini-ITX Case Link
I'd let either one go for $50 shipped in the 48 US. The C134 is used. The Voom is brand new.
I've got a flexible riser card, but both of these cases are may be too small to use a full size PCI card. I have used VIA mobos in the C134.
