Could also be mineral oil wicking up the cable, there are the absolute madmen who opt for oil immersion cooling their rig

Seems like the water is coming from the left. So the wall not the PC.

This looks like the “switch” or “router” end of the cable, so it could be coming from the PC

Oh man you're right. Two ethernet cables on the right. So yes it's coming from the left.

Could be oil from a PC or water from the wall.

Might not be a PC but a security camera or some other outdoors mounted device

From what I know, the mineral oil builds are usually more for novelty than utility. Mineral oil isn’t a particularly good heat conductor, and it’s several times harder to push around than air is, so it’s not great for efficient thermals. It’s usually just done as a sort of “lol look at what I could do” build by people who have more money than sense.

Agreed, the only argument for oil immersion cooling is, AFAIK, better energy efficiency which is of course not a real consideration for high end consumer grade hardware. A previous iteration of our national compute cluster was oil immersion cooled but the tradeoffs in maintainability etc. were not even close to sensible so the next iteration went back to regular server racks. And the iteration after that needed the floor space and finally dialed in the end of oily door handles and eerily quiet but oppressively hot server rooms.

The cable is probably routed outside (likely towards the roof) in a humid environment with the indoors end being at a lower pressure. At night, when the air cools, the humid air would condensate and start dripping out

Or it's just routed outside and it's normal indoor cable. The sun made the cable brittle and the insulation shattered, leading to leaks

I worked for a wireless ISP that had this problem with one style of dish we were using and this was the solution the engineers wanted us to take (just stripping the insulation to let water drip out before it got inside anything).

It was dumb because the POE the line was going into would very easily catch fire if water was introduced through the Ethernet cable. We had alternative dishes that we should have been swapping out for, but of course they wanted to save money instead of being safe.
