Nothing special for a case, but I had an extra motherboard and cards. I sold it to danbeaver I think?
It had a Prometheus PCI which looks ragged as hell no matter how you install it and the cables aren't that clean, but it was simple to set up.
The only slightly odd part was where the joystick/mouse ports mount and even that wasn't too bad. It might be perfect in some AT cases. No drilling at all, just bolted right up like any other AT size board.
