I think I have a Radeon 7000 in my 8600, which was pulled from an Xserve.

System Profiler says it is running with a G3 427MHz Processor with 272MB RAM (64*4+8*2). Got Mac OS 9.1 installed but I'm not sure how to use the capture card yet. :-/

I'll try to install OS X with XPostFacto later Just thinking of which version to be installed - maybe Tiger, if not Cheetah.
