Emax

OK, I'm slowly collecting parts thanks to Ted to make an internal CF drive for may Emax II and then upgrading the front to a slim+CF front.

came across a few links that may be helpful to others who are doing this.

IDE to CF with faceplate: $16 each if you order 2-4. The site has a minimum $20 order. Haven't gotten one so not absolutely positive it will work but the price looked good :).

IDE extender with 40 pin male to 40 pin female $4.88

they also have the power y splitter $2.47

another option to twisting the wires also, if like me you have a bunch of old IDE cables lying around would be to use 2 cables and 2 double ended headers, the second header and cable would do a second flip of the even and odd pins putting them back to the original.

Anyhow when I get everything up and running I'll post what exact parts I ended us using.

Thanks again Ted.
BTW did I remember right that at one time you had some slim drive kits that available?
