Shout out to Immich memories for reminding me of my surprisingly successful attempt at Homelab full mineral oil submergence coolant on 5-2-19, in this case, using 2 Raspberry Pi 3 B+s, a ton of velcro, a suspicious doordash oil of solely mineral oil and a wall flower half sphere vase from Amazon.

I still use those Pis today (in normal atmosphere of course), but yet despite several alcohol baths and scrubbings, are still sticky to this day with oil traces.

Still interested in the concept to this day, but would definitely need a proper workload to make it worthwhile, plus fans to circulate the heated mineral oil, but maybe aquarium Series X one day? /S, or is it? Dun dun dun!

I remember my old computer teacher in high school had a liquid silicone submerged PC in a fish tank with regular PC fans moving the liquid. Was pretty cool, but I always thought it'd be really cool to put some sort of luminous particles in there so you could see the flow of the current

Love that and that's quite a good idea, especially some over engineered on demand injection system for UV particles, either via a simple servo driven syringe in the submergence solution, to some kind of modified aquarium pump, combo with timed activated dark lights 👀.
