Ok, I have a fridge that is on its last legs. Its a standard horizontal split kitchen fridge.

The goal Is to turn it into a case for my cluster of PC's and cool everything with water. The radiator will be a 29" x 23" x 2" re-purposed central air evaporator. The radiator will be passively cooled outside, though putting fans on it may be an option. (Under a carport that is shaded 24/7, though outside ambient temps may rise to ~100F in the summer here)
*edit*
I also have a full outside unit condenser coil available if extra capacity is needed. May be able to mount evap coil in a box on top of the condenser and use the existing fan on a thermostat to cool both.

It will have five systems inside, and could probably house eight comfortably.

The largest issue I see will be PSU wiring. I plan to use the upper freezer section for PSU housing, with plugs integrated into the center for the PSU's to plug into. These will be, in effect, lead extensions up to ~5 feet. Are there any issues with combining all of the individual wires of a voltage rail into one larger wire (having a single heavy wire for each voltage) and breaking them back out at the motherboards? I have an abundance of 12ga wire to use for the project, so I was contemplating using that for the majority of the length and having bus bars at each motherboard location to break everything back out to standard PC wiring harnesses.

Here is a list of end goals.

  • KVM integrated into door
  • Panel on side with I/O for each system
  • Integrated GBE switch
  • Literally ZERO noise
  • Nice looking finish in black with stainless fixtures.
  • Panel integrated in freezer door with power, reset, and UV/Blue power/HDD indicators for each system.
  • Internal light working, for use as a work lamp.

Not using the fridge for cooling at all, just as a case. The cooling part of the fridge is going to be removed for weight savings.

Cooling will be handled by a double redundant water loop that is cooled by outside ambient air. The water loop will be able to dissipate 3kw+ of heat, possibly more given the size of the heat exchangers. For reference, each heat exchanger makes a V8 car radiator look small.

Just to re-iterate, the fridge is just going to be a cabinet with a water loop cooled by outside air.

Think of this project as "building a custom water cooled rack from an old fridge carcass".
