A Pegasos 2 would probably be better since it is much more powerful and will probably be a good bit cheaper than than CSPPC. CSPPC and CVisionPCC can easily cost more than a Sam440flex plus a used PPC Mac Mini. If you do manage to find an old PowerUp board for sale it's worth weighing up the cost options.
The newer hardware will provide a lot better user experience. The CSPPC is also limited to a much older version of MorphOS.
