Description

A few years back, I built a computer into a small fish tank to see how it would look/work with the mineral oil. I used cheap parts because I didn't want to ruin expensive ones on a random project. The computer sits on my desk at school (I'm a teacher, last two images) and students always ask about it and ask why I don't have fish in it. So I explain that its mineral oil.. blah blah blah. This gave me the idea of wanting to find a way to have a computer in mineral oil with fish around it. GIGABYTE beat me to it with their build but this summer I did finally get to build my version of it. This also gave me an opportunity to solve a few issues I had with the first fish tank. One of these issues was oil wicking. Oil would travel along the wires coming out of the tank and make a mess on the power cable and the hard drive. To solve this, I actually cut the power cord down and plugged it in to an extension cord. This breaks the suction and the oil does not continue down the extension cord. Another issue was that I forgot to take all the stickers off the hardware. Mineral oil eats away the adhesive so the stickers end up curling and falling off.

I had originally wanted to make the inner tank out of plexiglass but when I tested my creation with water, the seals blew out. Wasted some money to decide it was just easier to buy a smaller fish tank and prop it up on plexiglass supports. The computer is in the small tank, covered in mineral oil. Surrounding the tank is water with my turtle, Emerald, and some small fish he hasn't managed to catch yet. I have a couple USB LED light strips along the front rim of the 75 gallon tank to give the tank a cool look. The part list doesn't have the prices anymore but the R9 Fury X came from another build. The rest I bought new for this build on Newegg.com.

My plan is to use this computer as a media server holding files for access from my home audio system and other computers in the house. I built it more as a conversation piece than anything else as it resides in the entry way of my new house.

Cool! So you can just replace air with mineral oil, huh? That would conduct all the heat & none of the electricity, I take it. What could the turtle be thinking about all this. . . .

Yea its pretty neat. The computer at school stays at about 95-100 degrees F so its warm to the touch. Inside the fish tank, it will stay cooler and also heat the water so my turtle stays warm through the winter.

how does this work, pc parts directly in water? ;-;

  • 4 months ago

The computer parts are in mineral oil inside the smaller tank. Mineral oil does not conduct electricity so the components do not short out.

It was a fun build, both times. I suggest he do it with parts he doesn't care about for a first attempt.

+1 Awesome build. Now time to add Corsair RGB fish. Or even better, electric eels to power the system!

Awesome build. This is great for people who don't want to pay for expensive water cooling. The whole thing is water cooled.

Wild to think of entire server rooms being submerged

Wow o.O I did not know this was possible. The computer parts are sitting and surrounded by mineral oil? What even is that.....and how does that work? Dang.

Mineral oil does not conduct electricity, therefore it does not short out electronics.

I can't imagine how many nerdlets your little desktop build has and will inspire.

Nice build. Are all the parts in the mineral oil?

  • 3 months ago
  • 2 points

Yep, entire computer is submerged. I didn't use a hard drive in the build so I'll have to add more storage later.

  • 3 months ago

Can the hard drives be submerged too?

  • 3 months ago
  • 1 point

Not really, the moving parts of a hard drive don't do well under the oil. Those would have to be connected outside the oil.

my idiot brain thought that the entire system all components put together was $66.98,

  • 4 months ago
  • 3 points

Yea I tried to figure out how to change that but since the parts are old all the vendors don't have prices for them anymore. The entire build, including the tank, mineral oil and accessories was probably in the $1600 range since I already owned the R9 Fury X from my gaming computer.

I'm pretty sure you can add custom prices

  • 4 months ago
  • 2 points

I tried but I think since I used a saved parts list from back when I put the list together, it won't let me change them now? Maybe I'm just dumb?

So how does the turtle breath? Is it in the oil!?

  • 4 months ago
  • 2 points

The turtle is in the outer tank, which is just water. Only the small tank is filled with the oil.

how did u get old-*** parts

  • 4 months ago
  • 2 points

For the first build? I just bought old generation AMD parts for like $400 total. The parts for the new build, I bought new.

Also why did you put 32gb ram in an i5 system? how is it cooled?

  • 4 months ago
  • 2 points

I figured more RAM wouldn't hurt and since it will eventually be a server/media server, it'll allow for more use at the same time. Besides, I'm not sticking my hands in the oil to add more RAM later /shrug. The entire system is cooled by being submerged in the oil. The heat from the components dissipates into the oil and the oil passes the heat on to the water. Keeps the entire system below 25 degree C and it runs 24/7.

ok, well I still would get a Ryzen 7 at that point, but hey, it's your computer.

  • 4 months ago

Probably not a bad point. Would have saved a little money most likely. I hadn't built anything with AMD for a long time though.
