Finally, it's alive!!
I fixed a wiring issue with one of my video cards that was causing some boot issues. Turns out I had swapped a ground with a 12v pin in one of the connectors I built. Once that was corrected, it booted up just fine. The next issue I ran into, was the cooling loop didn't seem to be working. The CPU and Video water blocks would heat up enough to burn your hand and then the system would power off. Temp monitoring showed the CPU would go from 30C -ish (ambiant) to about 70C and then shut down.
A water loop is a simple bit of plumbing, so I was really frustrated that I couldn't get it running right. I checked the pumps and they were vibrating so I figured they were pushing water ok (may get a flow meter at some point). I had been rocking the case to remove air and filling the res quite often, but still had the same overheating issue. I also checked to be sure the tube routing was correct in and out of the pumps and the CPU water block - and it was.
At this point, it could only be one of two things:
1) there was still a lot of air in the loop - most likely due to the two 360 rads on top above the filling point in the res
2) the jet plate on the CPU water block was put in backwards. I inspected the block before installation, and could have possibly installed the plate in backwards in error resulting in the path being blocked.
I disconnected all of the PC equipment except the pumps and the fan controller, and then let it run for a day and a half. Before and after work and bed times, I would rock the case around and refill the res as needed. Finally, I laid the system down on it's side for a few seconds, and the res emptied completely. I'll admit I was a bit shocked to see it drain so quick. I refilled the res again and repeated this process once more. There must have been a huge air pocket stuck in one of the reservoirs that couldn't clear until I laid it completely over.
I tried booting the system again, and I am happy to report that the CPU is holding at a steady 29C at idle (ambiant) and all of the blocks are cool to the touch. I haven't done any benches or OC's yet, but those will be coming.
I'm elated, and my wife was almost in tears at the thought of getting all the parts of this project out of the various rooms of the house. No real pics at the moment. The wiring is a mess as I was doing a lot of testing so everything needs to be rerun again. I'll be spending the next week or so getting the lighting done and the server up and running.
I'll post some pics of the lighting process and final pics soon.
Thanks for sticking around - this was a long one . . .
