Large case for retro pc needed

Hi Folks,

I'm building a retro pc to run Windows 3.11. I have a Soundblaster, MGA Matrox Mystique SVGA Video Card, ATX Motherboard, everything. Including a Creative Labs 3DO Blaster. The card itself is an ISA card, the problem I am having is finding a case that fit the 3DO Blaster. The card is 33cm (13in) long. And because of the HDD caddies, it doesn't want to fit in the large modern cases I have.

Any tips?
