Radeon card for Cube


I know for a while Apple was bundling the Cube with the Radeon card. Although this card was AGP, I don't think it was the "standard" Radeon AGP, as it had some sort of modification (fanless? shorter?) to fit in the Cube.

Is there still some way to get ahold of these? There is a Cube with the older Rage card which I would like to upgrade to the Radeon.
