The Cyberstorm Mk 1 actually runs faster than the Mk 2 from what I've heard. The benefit of the Mk 2 is that it contains a SCSI module built in and isn't modular. However the A4000T already has SCSI so the Mk1 pips the Mk2 for A4000T use. Saying that the QuickPak 4060T board is the best as it uses EDO ran and runs at 55Mhz as far as I've heard. Then the Cyberstorm Mk3 and then the Cyberstorm Mk1. If you want a PPC you are limited to the Cybertorm PPC boards but they are pricey and software/functionality of PPC classic machines is limited.
