I never was a big fan of the hard tube water cooled PCs but a couple months ago I saw one with copper pipes and I was amazed. There was no question that, sooner or later I would build my own variant, and here it is. The build went fairly easily and smoothly without interruptions, except at the very end when I did a pressure test with the EK leak tester at 0.75 bar and the pipes popped out several times. Since I’ve never done this before, it turned out I didn’t tight enough the clamping rings. As a final touch I put a cover to the top made from top grain leather. Oh and soundproofed the case using butyl automotive sound deadener with much better result than I expected, now I can't hear out the HDD and no rattling from the panels.
