Looks pretty epic man.
Here's an idea to help with extra condensation in the mean time of building a chiller..... insulate a dryer vent hose on the outside, and run the lines going to/from the a/c unit inside the hose, allowing cold air to be blown along the lines, and all the way to the motherboard, keeping the system cooler outside of the blocks and hoses, reducing condensation.
Any condensation should then be only on the outside of the hose.
