Ramiel Part 2!
Nope, had to fix this problem. Thankfully my favorite etailer had a solution on sale for the time. Yay for twin 5970s!
5970s *do* clear the cages in a 500R, albeit barely.
After a lot of testing and burning in, I found clocks where the cards and temps would be to my liking. Any higher core and the stock voltage was not enough. I also did various tests with my KAW and Overvolt to see how high the cards could go. Found out though that even though they could get to 900+core, the heat and fans simply was too high and the system went from ~700 watts to 1,000. Enough of a power increase that with efficiency factored in, I could not push the PSU any higher I think. Obviously they were backed down to what the image below shows and it's been running great since.
Finally as can be seen, I ripped out the drive cages to help the airflow. It's dropped temps by a couple degrees overall. The HDD has foam sticky pads on the bottom to keep it proped off the case floor.
--------------
Thanks for letting me share my building experience and what I'd hope is a pretty clean (IMO) mining rig. It may not be the most efficient in terms of price but I'm happy with the challenge it presented and feel the investment will pay back eventually. Currently getting ~1.5GH/sec with it. The only heads up is that with pets and so much case airflow, that the system would need practically a blow-out every week for the dust it'd gather.
