A few years back on Ebay I remember seeing some Color Classics that had been upgraded with either G3s or G4s. Does anyone remember seeing those? They may have just been Cubes put into a PCC, but I am not sure.
I've always wondered how they were done, and if any were left around for sale since they are pretty cool. I remember seeing them in the early OS X days so the systems mostly came with OS 9.2 since it was before the release of XPostFacto. It would be pretty neat to see one of these or even build one if anyone here as the expertise to do so!
