lastly if it worked a condensation detector on the psu block linked to the hardware shutoff maybe another wise precaution, for the odd time the humidity was very very high?
The problem is that in worse case scenario you'd get condensation just about everywhere. Assuming the blocks , peltiers, are perfectly isolated , front and back. If any condensation appears inicialy, it would be on the tubing. And start to run on the motherboard , cards , the works.

So, at least for me, it wouldnt be particulary useful to have a condensation sensor in the PSU, where it is in a "box". Unless it has a benefit i cant see.
The problem is that , in the project , the floor is the radiator, so a detector cant be placed on the bottom of the case (where usually things drip the most).

So, unless the detector works near (or ON) a tube (the main intake should work) , it will be difficult to detect condensation, IMO. I think it would be easier to detect humidity levels. There's a few sensors around, cheap.

http://www.relative-humidity-sensor.com/ , example.

The ideal would be to read the temperature of the exit air from the radiator , the temperature of the exit air from the chimney , and with the reading of the humidity levels , control the chimney heating. A small uP could do that, similar to a circuitry i think i saw around the forums , i think it was Turbokeu's. Then there'd be the calibration problems , etc etc etc.

Oh and if I burnt myself on the hot chimney It would be the first and last time...... perhaps I should have "numbskull" embossed backwards on the chimney
Nah, emboss a dragon or a tiger . If anything happens , at least it would look real cool .
