The Optiplex GX110 User Guide states that there exists for the Low Profile desktop model an optional PCI/ISA riser board to replace the PCI riser board that comes with the system.

I have been looking for this riser board for almost a year now and in the process ended up accidentally purchasing a GX1 riser (which does not fit due to a completely different edge connector) but have yet to even see a single photo or find the part code of this mythical piece of hardware.

If anyone has it, can share a photo or part number for it, or even better supply me with one, I would be eternally grateful.
