Nice. I'd like to see how it all fixes together inside.
Lots of users including myself have their CF card connected to the IDE removable from outside.
My technique was to glue the 2.5" IDE->CF adapter to the top of the internal PCMCIA connector and then increase the height of the PCMCIA slot in the case using a series of fine files. This makes the slot much cleaner (and easier to do especially for a novice) than cutting a hole in the case with a Dremel or something.
