If you can't find a Cyberstorm PPC, does your alternative need to be a Cyberstorm MKIII? Unless you are wanting to use the CVPPC card or PCI expansions available for these boards, something like the GVP-M 4060DT would be just as good (although the SCSI controller isn't as fast as the Cyberstorm one) and I believe Software Hut in the US may still have some re-manufactured (ie new) ones available.
