Goose, your going well but ... you must drop the "saturated" stuff.
Doesn't exist when talking about atmospheric events. It's a wrong concept.
Confined gases/liquids can be/get saturated. The atmosphere (and including oceans) doesn't, it looses significance when talking about a
open system of that magnitude. That's why it's a "relative" humidity.
It all about energy balance and transfer in the natural condensation/evaporation events. It's a constant process.
To give an example , sulphur expelled from a volcano as a vapor sublimates to solid state. The atmosphere wasn't saturated. The super heated vapor just lost energy to the surroundings and the energy balance was altered abruptly to the point it no longer had energy to maintain it's present state. Same goes to water vapor in contact with different surfaces at different temperatures , with different air temperature
.
To give another example , in the outskirts of the Sahara Desert, you can have up to 100% RH , and no condensation whatsoever during the day. But in theory, it would be saturated and condensation would be forced (which does not happen). But as night falls, things literally freeze over. Lots of condensation occur (and ice) because of the balance shifted with temperature to the other way, surfaces dropped temperature considerably and energy is removed from the water vapour.
You can have just about any temperature / RH combination. And not have huge amounts of condensation or evaporation (uneven balance).
What changes (and we are discussing) is the Dew Point in those combinations when in contact with a temperature differencial (surfaces or air fronts).
I know it's a tricky subject.
I dont know how to make it more clear, language differences isnt helping either. Maybe it's my fault (probably).
A Dehumidifier re-heates the air to minimize temperature diferentials between the ambient air because it's not his job to maintain cool air. We just want less RH.
Anoher thing you're missing.
The interior of the case is not the main issue. The blocks and the tubes are because they are well below ambient, a few inches can have a delta T of several degrees.
Bladerunner assumes , if he can get the new ground rad, 8 ºC intake, even cooling pelts , it can go up to 12 ºC ... maybe 15 ºC on worse case scenario , not more that that I think. Equal air temperature of air passing (lets say those 15 ºC) and tubes will yeld no condensation because the delta T is minimum , even with high RH (if the radiator forces no condensation). Which if goes according to plan, will. Cool air, less RH, lot less risk. Of course, if things are tweaked properly. May assumptions. You dont need to heat up the air. I dont even think you should. It can shift the balance towards condensation if the delta T is high enough, given the cool surfaces of the blocks/tubes.
If , however, no insulation is used (i strongly advise against it), temps will depend on the cold side of the pelts. Things get even more tricky there. You'll have to know how low can the pelt go when crunching numbers , playing a game, etc. Some degree of control will be necessary, IMO.

Agreed completely, except that I'm not sure the rad would do well enough.

You head him BladeRunner , make it happen
