No problem, you are welcome.
Thats sounds wicked!
I had a dual rad too, but I have a Antec P180 and couldn't fit it in without some serious dremel work! I've changed it to two single 120mm black ice Xtreme rads and fit them in the case with minimal modding (lost the hard drive hold with the toolbox but in the top compartment). I got it so the front rad has a fan sucking in over the rad, and then the back rad by the cpu is sucking in over the rad, still leaves one 120mm fan to exhaust in the roof of the case. I currently have it setup like this. pump-rad1-cpu-chipset-rad2-gfx-back to pump. I've only got an A64 4000+ and a 850XTPE thingy! But the cpu runs at 24C at idle, not check under load yet. Gfx is 30C idle. Not sure how these compare, but it helps being in England where its damn cold already!
This watercooling stuff is rather addictive!
I'd be interested to hear/see your results m8. Have fun and take care.
