Sweet... I was very happy when I got my CSPPC late last year and it sure is impressive.
I would say that WarpOS is better... it should also be able to "emulate" so powerup software will run if I'm not mistaking (not played around too much with that system yet actually so can't confirm that).
What to look out for is quite simply... heat. The heatsing/fan for the PPC is ok for "minor" PPC work but I would not recommend running OS4 with it so you will probably need to customly manufacture a bigger heatsing to use the existing "holders" and put a fan on that. The PPC is however quite delicat so no 300g cobber blocks please. Same for the 060, it sits in there are get quite hot so at least put a heatsink on it (causious me also added a fan for this one).
