I give it 2 weeks and someone will be trying to mod one of these things into their new gaming RIG.

Two weeks, and minus a few decades.
An 'immersion heat sink utilizing forced convection [in] single-phase immersion cooling" means a regular HSF in an oil-immersion rig qualifies: there's 'forced convection' (fan on heatsink), the system is immersed in the fluid, and the fluid does not boil (so remain a single phase). Even if you want to be picky and demand not using mineral oil (because its sticky and gross, potentially flammable, and has nasty effects on polymers found in common components) and instead use a dedicated immersion cooling fluid like Novec or Fluorinert, then That's still multiple decades ago! And that's just for 'traditional' PC hardware; immersion cooling for mainframes and superconputers stretches back even further (e.g. Cray T90 series).

Man you are such an spoilsport, he was joking about the 1000W just for the CPU part.

Alrighty!

Yes indeed! I'm sure someone will step outside the boundaries and try it regardless of risk or cost.

So there's a cooler all ready for 15th gen I9's.... Cool.

Having worked with liquid cooled Crays, Fluorinert isn't supposed to boil. BUT it can. And when that happens you have to notify the EPA, because you just released the equivalent of 100,000 cans of hairspray propellant .... https://en.wikipedia.org/wiki/Fluorinert#Global_warming_potential

HFCs: making CFCs look like regular Cs!
The Crays (and most DIY projects splashing out on HFCs) are single-phase by design, but there are a few who have intentionally chosen the low-boiling-point mixes for low-temperature phase-change use - clamping component temperature to the fluid boiling point. Ideally these are closed loop with a condenser/compressor - usually not for environmental reasons but because the stuff is too danged expensive to run open-loop!
