Here's some pics of the project I now declare finished. I managed to heat the water to 80C (forgot to plug the rad fans in...) and that caused a leak destroying the mobo and GFX card. Replaced them and it's now working fine (except for some random blue screens, maybe due to that second broken card i still have in there.
I hoped that the card was still alive and ordered another with a waterblock to have quadfire. Well... it didn't work. Anyhow, here's the picture galore.
I'm going to make a sticker out of this and have it on the window.




Plasma cut sheet metal. I printed the pic on paper, cut it and then draw the outline to the metal. Then I cut it freehand and got lucky.

It's nucular powered!

Lights on

So here it is. Learned a bunch of things and next time I won't do nearly as many mistakes and I can do many things the easy way. As soon as I get my assistant computer engineers (8 months and 4 years old) away, I pull that bad gfx card away and maybe bake it to see if it will work again.
So, until then....
