New Build for 2020

I am about to start a new build for 2020, I have collected all the parts and then some over the past decade.

Hopefully next week, I will start breaking stuff out of storage and start documenting a bit more as I go.

Addressing some of the issues with my current three stage:
Capacity at 3rd stage is my biggest concern.
Getting it to fit into my selected box on wheels.
Running more power into my office.
-150c with 1000W capacity.
Updated block design.

I will start posting images for part selection and I will restate this offer more than once.

If you see anything that you need or could use please speak up. I have multiples of everything and I would like to see this odd hobby live on.

At some point I will put the tripple stage up for sale and it lives on another 18 years. Yes, I started the build almost 20 years ago.

waw 1000w and -150c sound a lot , i mean a lot a lot .
what will it cool ? more than 1 evaporator head ?
anyway good luck with your build :up:

I want to be able to connect to a socket 3647 or AM4 with results.

if we talk 32 core + than those 1000 w cooling power make sense ,

What refrigerants are you planning on using for each stage?

R507 ICEON89 R1150 most likely

I am re thinking compressors

-150 at 1kw heat load ? Well then you can foget about a 3 stager cascade ...you would need 4 stager cascade in last stage R50 refrigerant ...
i would go with:
1st. R452a /R404a/R507
2st. R170
3st. R14 ( or mix R1150/R50)
4st. R50
to hold souch of LOAD in last stage you need 3 phase compressors , first stage should be HUGE , power consumption will be so large that you need dedicated line for this cascade :)
i will looking to see the build progress!
