Question I am looking to build a crypto miner for the fun of it and a display piece

[Trixr]

Currently, the plan is to use 3x 5700xts for 100$ each, a generally reputable mobo with a custom printed frame, and purchase three risers for the mobo that will feed inside of a glass tank. Inside this tank would be mineral oil. I have little experience with miners or how to run them properly much less how to run a tank but if I had to guess the proper prep would be to deep clean the 57xt's and then proceed to run them in the cleaned tank. Keep the tank air-tight and swap out the oil after a while to remove as many impurities as possible. continuing from there it may be a good idea to purchase a motor that can move the oil around to replenish the contacting oil on the chip. I was considering 98% isopropyl with an air-tight seal and a powerful motor to create a very fast-flowing current but after doing some reading it may not be as effective or reasonable as I hoped.

I should have given more details on the reason for the post, I'm looking for suggestions on what parts to go for and the best method to cool the GPUs or whether it's even worth it at all. I would think running a triple 57xt setup on a GPU-optimized group miner for 400-500 bucks would be quite the story and possibly see it break even after a year or so. I'm entirely ignorant and clueless if you couldn't tell but please correct anything :3

1. Crypto mining with GPUs is dead dead dead. At typical US electricity prices, the calculator at Nicehash gives you a 'profitability' of negative $0.40 per day.
If you convince someone else to pay your elec cost, you 'earn' less than $1/day.

2. Mineral oil. That is a fun show piece, nothing more.
And a major hassle.

Aww, well I still wanted a fun project, any suggestions?

Project for....the mineral oil?
Not in my wheelhouse, except to say "I wouldn't"

An old triple SLI water cooled setup perhaps? No real practical use other than playing old SLI supported games.
