Finally I decided to work on a proper cooling system.
Brought home a mini refrigerator from Lowes for $69.
Not sure if I’m disassembling and dropping the cooling element/temp sensor inside the water bucket or if punching a couple of holes and putting a water reservoir inside the chamber. Probably going with second option.

I was thinking about this approach with a copper coil inside the frig?
@donkjr that was my idea also but I concluded I would still have to have the copper submerged within the fridge to increase the temperature transfer. toying with peltiers atm instead 
and yes I am diligently stalking that post you tagged earlier, hes got the right idea.
@Domm434 I like the peltier idea but it seems a lot less efficient and a lot more $ than a small frig. with a coil or reservoir.
yea i can see that. as i already had the ssr and a potential controller all it cost me so far was the peltiers(8x 12706 for 15$ on wish). Hoping the operating cost in Kw/h is not too high in comparison to the mini fridge. could be a better cooling device though, potentially able ot handle heavy usage and the fluctuations thereof.
These fridges are frequently cheap/free, especially when the semester ends at colleges…
I think adding a reservoir in the fridge with a cool in the reservoir should work well
Any plan to swap out the pipes and heat exchanger?
Could go pretty small with that setup, i used a similar sized compressor to cool a PC years ago 
I’m confused… are those the hot coils…
@Josh_Rhodes Yes
