Here you go folks:
For those who don't mind some major hacking and fitting for your 5500/6500 based Power Color Classic this guy has 20(!) L2 G3 500MHz cards available for $69.95 each!
If I had some money I would try and make a deal on five or so for future use!
No connection to them, etc. just an interesting item.
I wonder if anyone will ever write a OS X driver for this thing? Couldn't be that hard :^)
