Very beautifully done but I can only wonder what the pc will weigh once it's complete. Also on another note how do you get so many bubbles in the reservoir?
Thanks very much, welcome to my little project! I’ve still no idea what the final weight of this will be once complete, but it’s sort of a moot point now since I’m definitely not going to be able to lift it.
To answer your question about the bubbles, there are rather more than normal in those pictures – because the system has only recently been refilled – but the cooling loop layout is deliberately set up to produce that effect. There is a split-return at the final point on each side of the circuit, producing two vertical jets of water from the top of each reservoir. These strike the surface of the water in the cylinder, dragging small amounts of air down with them and mixing the fluid around. This is what creates the swirl of bubbles; moving down the tube and then back up again in chaotic fashion, though never far enough to risk reaching the very bottom and getting air sucked back into the loop. They catch the light from the fibre optics, contrasting against the black background placed on the inside of the sleeve, producing the effect you see there.
Unfortunately the idea hasn’t quite worked properly. It looks really good like that immediately after each system start up - exactly the intended look - but after a while the bubbles become really fine, all but invisible. Sometimes the effect lasts for a long time (several hours) and sometimes it doesn’t. Sometimes the GPU-side reservoir has coarse bubbles and the CPU-side has fine ones, sometimes it’s the reverse. Invariably one of the reservoirs works better than the other. I’m still trying to work out exactly why...

You need to win an award ... Not sure what but something haha.
Congratulations not long now
I think the only accolade I’m likely to get for this is the certificate declaring me clinically insane. Maybe I’ll get awarded my very own straightjacket as a prize! They can monogram the Ironbeast

There are a couple of little bits and pieces still to finish off before we’re ready to transplant the hardware. At that point I really do have to blitz the next bit as quickly as I reasonably can, to minimise the computer-less downtime as far as possible. So fingers crossed you can expect to see a big jump soon, from glorified indoor water feature to actual liquid-cooled PC, I hope over an uncharacteristically short space of time. Then it’s on to the case panels…
