Seems like a good find. But, I could not find capatibility for either Porsche CDR-220 or the Becker CDC-3 (aka Silverstone Model # 2660). They do have one for the Silverstone 2630 (but only in the Pro, Classic and Extra models) and this may work, but someone else willl have to be the guinea pig.
Also, you'd have to figure a way to cover the unit since the access door will be open and subject to dirt, dust, etc. This wouldn't be too difficult though, some kind of shrink wrap comes to mind.
Please report back to us and let us know how it works for you. It'd be an exciting way to do the conversion.
