You can get a 1.67Ghz G4 Mac Mini on eBay with OS 9 preinstalled. It's wicked fast (especially with an IDE SSD adapter)
There's faster single thread accelerator cards that were made for a while by a guy on the 68kMLA forums, but that was many years ago. I think Action Retro on YouTube has one that broke 2Ghz
