Mike - I received the new cable and finally had a chance to try it out this weekend...this build has been very slow because of my insane hours at work. It works perfectly! I was a little worried when you posted that it was shorter - you can see from my pics that mine is set up differently than any other I've seen. I lowered the Video card bracket to allow one card horizontal and the other vertical. The card also has to be in the outside position on the bracket in order to clear the "back panel" bracket so length was a concern, but it spans the distance just right. I have a few more goodies to add and I'll post a proper project summary with lots of pics.
Thank you Mike, ya done good!
edit: I just realized, that one photo with the acrylic in place shows the two cards both horizontal which I had to do while waiting for the new cable...so glad the new one worked!
