You're looking at a much less ambitious hack for a QuadraIIci/IIci040/IIciQuadra than my Quadra 7100 was. You'd only need to graft the ports section from a compatible case for a pseudo-stealth hack. Meanwhile you can cleanly excise the rectangular ports opening in preparation for the graft or just savage the IIci's ports section with a dremel per Al's warning in his (linked in previous post) LowEndMac article.
