I'm baack... sorta...
Guys, first of all... Sorry i vanished. Family stuff got in the way, both the bad and the good kind. The good being +1 family member in training.
Anyway. AHowes, i tried to answer that pm you sendt me in the middle of it all, but i have too low post-score to pm and... Yeah, i kind of gave up. Sorry.
As you guessed i used the screws that came with the 780waterblock+backplate. I was kinda cowboy-fitting them on as they where coned and i had no other screws handy. I'm sorry i wasn't clear about that and that i wasn't able to confirm the mm's of the tim-pads in time. Glad you got it working, though!
I'll try to keep an eye on this forum for a while.
