Ps4 water-cooled in pc?

Montanablack has water cooled a pc with built-in ps4. How much does that cost? Can be a normal pc or even without a pc. Who does something or sells something. Or are there just people who sell water-cooled ps4en?

There used to be some of these PC & PS4 water cooled systems, but as far as I know they are no longer sold.

You can actually google for "watercooled PS4", everything I saw at first glance was decent and will help you.

I have often read 3000 euro including PS4 in terms of costs, but will also be cheaper with an AiO. But it takes a lot of effort

You can buy something like that, of course, is a little superior to air cooling and looks really cool, but I would rather advise against it, since these are much more expensive.
