Hmm something's wrong here or i misunderstood. Let's review the different solutions

I'll use the following syntax:
+Element
[Heat transport medium]

Conventional watercooling loop:
+Core
+Waterblock
[Water]
+Rad
[Air]

'Usual' phase change loop: (quite easy)
+Core
+Waterblock
[Water]
+Chiller (evap)
[Toxic stuff]
+Chiller (condenser)
[Air]

'Vapochill-like' phase change loop: (quite hard)
+Core
+Chiller (evap)
[Toxic stuff]
+Chiller (condenser)
[Air]

In a 'usual' phase change setup the evaporator *should* be in contact with water.

Putting a water loop in a fridge does the following :
+Core
+Waterblock
[Water]
+Copper loop (or bucket or rad..)
[Air]
+Chiller (evap)
[Toxic stuff]
+Chiller (condenser)
[Air]

You're just adding a layer... No good, not efficient at all. Air is a very good insulator.
Why not chill water directly ? That's what most "phase changers" are doing.

Besides you dont want to add any extra layer after the condenser. That would only hinder its performance.
And remember you don't want air *inside* the loop. Let air stay at the end of the process.

(edit) oops i just saw last BB2K post. Well, that's it, i just confirmed
