I've got these cards if anyone wants them:

1. Analog TV card - PCI. Has some particular chipset which can be used to decode certain UHF services, well, back in the day anyway.

2. Adaptec SCSI PCi card. AHA-2940

3. Matrox dual monitor card, PCI. I'm pretty sure I've got the external cable for this. Model G55M

4. Guillemot ISA Audio card. Was a bit special for having SPDIF I/O on a ISA card IIRC.
