phase change n00b needs help

I am building myself a case. I have been reading about phase change cooling and I am considering implementing some form of it in my case.

What I am wanting:
*Capillary Phase Change, Cooling Water.
*Water Pumped through to CPU, NrthBridge, GPU.
*40W-60W Peltier/s cooling reservior water.
*StampII based controller.

I don't know if this is unworkable or highly improbable but I don't believe it to be impossible. Money is no object but I wonder if this system can be done with these restrictions:
*12v Compressor
*CPU Temp under 0C at 100% load with some form of antifreeze or brine(if I can get stainless components made up)
*I'd like the whole system to fit in a perspex/aluminium box no bigger then 20mm sqr.
*As quiet as posible (30db or less)

So all up thats a Water cooled system with the water being cooled down to -0 temps by a small phase change system then the water being kept cool by peltiers to prolong the time before the compressor starts back up.

I'd like the system to be practical but i mainly want it for the bragging rights and the ultimate PC factor at my local LANs.

Can it be done?
Is a capillary system the way to go?
Can I fit W/C and Phase and Peltier in a 25mmSqr box?
Am I stupid and insane?
If I have stainless steel components can I run brine as my heat transfer medium?
Is the compressor from a car-camping fridge okay?

As I said before money is no object. The only reason I am thinking of this setup is I am worried about condensation. Direct contact Peltiers and direct contact phase run the risk. Another question:

What would a PC Dehumidifier do in the way of condensation?

Maybe I have lost my brain! The system doesn't need to be an elaborate Nitrogen cycle system. I would consider this reasonable and my mate was a qualified refridgeration tech about 15yrs ago and he reckons it can be done... so I leave it to you to help me see the light.

Sorry half of this isn't relvant but hell you seem like the most knowledgeable cooling people here.

THANKS
