Why so few immersion cooled custom builds/Mods?

[coin@coin]

Can you actually sell/re-use components used in immersion cooled builds once you take them out of the fluid?

Provided the correct thermal fluids were used (ones that do not attack rubber/plastic), of course. If you were using Novec it will simply evaporate. Fluids like those from Clearco will need to be rinsed off using alcohol.  In either case the miners will be pristine and probably a bit cleaner than when new.

Any new information on immersion cooling products?

Please ref https://bitcointalk.org/index.php?topic=1604125.0 dealing with liquid/immersion cooling a s9.

Mineral oil is NOT a good thing to use:
Only moderate heat-capacity (how well it absorbs/releases heat)
Viscosity highly variable with temp
Even when warm, is still not easy to pump
Attacks many plastics including Nylon (PCIe connectors), PCV (wire insulation) and elastomer (rubber) capacitor seals.

Much better choice are thermal transfer fluids designed for use with electronics and electrical parts such as http://www.clearcoproducts.com/dielectric-silicone-fluids-sto-50.html

Water-thin meaning easy to pump and flows very well around components, does NOT attack rubber/plastic, etc., very good thermal properties.

Silicone oil might not be a good idea for parts using silicone in them... Might be perfect for a transformer, but problematic for electronics.
Nobody will give you a certificate that all is well with his product.
This guys seem to know what they are doing: https://www.grcooling.com/ and it is said to be mineral oil.

If you read the specs on the Clearco fluids you will see they CAN be used with many silicon rubbers. Just need to verify it with the components used. The only silicon rubber component would be seals on large caps and I have already verified with a >6mo soak in ST50 that it does not harm the seals.

Mineral oil is proven to embrittle nylon and PVC wiring so that is right out of the picture. Now GRC may use a mineral-based fluid but that is a vastly different thing than generic mineral oil as found in a drug store.

It might very well be that it works, however it is impossible to tell if all the plastics used in all the components of a pcb are suited. That is the whole point and problem with immersion cooling - if it is your own hardware, you can surely just take the risk, otherwise things get complicated.
Novecs 3M is no different in this regard..
