PC looks-based builds aside, one of main priorities for LC is quieter cooling. Quieter cooling with quieter/slower/less powerful fans needs rads of less FPI (and higher size/mostly frontal area, but also thickness), which will mean that they will be oversized (harder to find mounting space) and will weight excess (also because most common rads/cooling blocks for PCs are from copper or brass, vs automotive rads usually being aluminum) vs high fins per inch automotive rad optimized for powerful fans (noise matters way less under bonnet behind firewall and near relatively loud engine), that can net same cooling even if being of 4x times smaller frontal area (thus also less weight and easier to find space where to mount in cramped underbonnet space of modern cars).
Also even though common pumps used in PC LC scene (eg. Laing D5 or DDC series) are also 12V pumps, not sure they will respond well with possible voltage spikes in power and IIRC they also were certified upto 60C, not temps one may see under bonnet near hot engine.
In short, not sure it's good idea.

The PC cpu heatsink/heat exchanger would not be retained, only the rad/pump/fans and lines that can easily be lengthened. Also this can easily be mounted anywhere far away from engine heat. And with fans doesn’t need direct airflow. A 24v to 12v step down converter is only 10$. I would be more concerned with how this holds up to the elements then its efficiency or engine heat. But it was just an idea to have a small all in one solution.
The intercoooler I posted that would be used is a small 4”x6” pipe that would easily fit in line with his system not increasing distance from blower to engine. He is not trying to cool 15+psi from a hot heatsoaked turbo. He is cooling boost from an electric supercharger that will make less then 6psi at 6k+ rpm. His cooling needs are not very much. So a small simple easy solution would suffice. a big front mount traditional intercooler is way overkill and would probably have more negatives then positives.
