If you have a dual 1.42 GHz CPU card (like from an FW800 or something), I might be interested, seeing as I'm plodding along with one as my main desktop.

Surprisingly, it works almost as well as the Mac Pro, only slower. The only thing that bugs me is that it doesn't run Windows (except via Virtual PC, which is far from ideal, but it might suffice in a pinch if I have to).
