No HDD on the CSPPC? Would be much faster than any other alternative (and would provide for proper termination).
To not obstruct any future expansions with highly specialized cabling, better use a standard wide cable, an adaptor for the 50pin drive and a bog standard cable terminator. If you want those real cheap, you can take a look at the various offers on eBay. Otherwise reichelt.de or extend.de have everything you need.
