Try submerging your console in mineral oil.
I know this is a joke, but I'm actually going to respond to it seriously.
I would like to do something like this. Not just with my consoles but with a lot of my stuff.
I have lotsa desktops that I'd like to do something like this with. Because I've done most of the upgrading that I can do to them.
I have an FM1 PC that has the best CPU that exists for it, and an FM2 PC that has the best CPU that is for it. And those sockets are being discontinued and AMD won't make any better CPUs for them. I already have a GPU as good as they need, and I have SSDs in them. They're around where I can't do many more upgrades to them, so I'd might as well do something like give them a kind of liquid cooling like that.
Mineral oil is nice. I don't know if mineral oil is a dangerous substance. But I've actually heard there's a better one. I forgot its name, since it has an all science-y name. But it's apparently better than mineral oil. So I would use that, instead.
For some new PCs I would still do upgrades to, I wouldn't do that. But for some of my older or outdated computers, like my FM1 PC, there aren't many more upgrades I can do. So submerging it in something like that and making it a closed system sounds nice.
And for a console, I would have to make sure there aren't any parts that are mechanical and could get ruined by being submerged. I couldn't do that with a PlayStation 3 unless I replaced the hard drive with an SSD. And there might be other parts that are mechanical that I couldn't do that with. I would have to be careful and make sure.
But the idea sounds nice. I would want to put it in another case, though. One that was better for being submerged.
