A long time ago (over a year, can you believe it) a guy by the name Joe @ Procooling.com put together a version 2 (I think) using the powerleap adapter. The overall installation was rough but worked. Based on the participants in this thread I believe a more elegent solution can be worked out. He also participated in these forums if you want to do a search, but the basics are all in the article. Below is a link to the article:

Here is a link to justdeals.com which has old "Smart & Friendly" external CDROM cases for $20.00. We have on of these old units at work and there high quality but are large and heavy. But I'm sure they'll give you the needed parts to start with. Link Below:

I've been sitting on three v2 for about a year waiting for a some badly need cash and confidence. The perfect I-Opener configuration for the Hacker/confidence challanged like myself would be:
Powerleap adapter - externally powered
Hard drive & CD drive - Externally housed and powered
I figure I need a nice base unit with a HD & CD that would power the drives the powerleap and the I-Opener. Then I would only need an IDE cable to the Base unit and two power cables to the I-Opener.
I'll Be watching this thread with High hopes.
Thanks guys, for all the info.
