Just looking out for all you techimoers out there.
I re-installed my watercooling kit yesterday (consolidated the two radiators into 1 Black Ice Extreme II) and installed a dual 5.25 bay reservoir... and after the dust settled - it wouldnt boot.
I was afraid that I had crushed the cpu core with the swiftech mcw5000 waterblock. i checked everything, from the 9800pro being pushed all the way in to even reinstalling the cpu block to make sure it made decent contact.
nothing worked. i was just about to rip an athlon off one of my friends computer to double check my suspicions of a crushed cpu...
then, i looked the the memory slots.... the latch on one of the memory slots was a little pushed back (maybe 1mm back). i pushed it in just a little... and....
it booted!
so, before losing all hope.... check the ram! lesson of the day... push all ram in and watercooling is a pain, but a blessing at the same time.
