I have a design for a rather unique build based on 3M™ Novec™ 7000 engineering fluid. I have started this project as my current box is getting a bit aged and taking longer then I would like to render some of the designs I have been doing.
- Use the least amount of Novec in the system as possible (it's about 330 dollars a gallon)
- Make the design modern and futuristic
- Crunch though CPU renders quickly
- Play games and look sexy doing it
- Use the next Gen AM4 (Ryzen 7 3700X proc or Ryzen 3800X)
- Able to run a Mini ITX and single GPU
- Build a system that allows for easy changing of I/O wires
With those goals in mind, I set out using Autodesk Fusion 360 to create the design. After about three or four days I got a design that was well enough defined to get a BOM going as well. It has a calculated need of about 1.3 gallons of Novec and has a "condenser system" created by a secondary water cooling loop. The design has a clear acrylic tube that allows the cables to be ran in and out of the tank more easily and per the design guide I found on 3M's site creates a “trap” seal that helps prevent rampant egress of vapor". The tank features 14 screws that hold down the top plate applying pressure to a O-ring. This should allow it to have a gas seal.
The cycle would be as follows. First the computer components heat up under load and the Novec solution phase changes when reaching ~34C. Next the gas reaches the 80mm triple radiator at the top of the sealed tank, It then condenses back into a liquid and falls into the pool. (I'm excited about this part as it will look like it's raining inside the tank) From there the heat is removed by the dual 120mm radiator that is at the bottom of the case pumping water though the radiator "condenser" contained in the Novec tank. The dual 120mm radiator is cooled by two Noctua NF-F12 fans.

Note this is not all the parts but the big ticket items.
So far I have the design and bill of materials all worked out, and the other day I was able to work a deal to possible get a pre-production sample of the HDPLEX 800W DC-ATX converter. I also have got a quote back for the custom tank. They are able to machine it as well, so it will save me some work. I have also ran by a local wood working store and picked up a good stock of walnut needed for the support of the tank. It will need to be planed down and then cut to shape as it is rough stock at the moment.
I plan on getting tank and measuring it to adjust the CAD model if needed. Then from there I should have a accurate enough model to send off for the case to be 3D printed. I first thought I would attempt to print it, but it is much to large for my printer and I did not want a bunch of seams everywhere.
I'm unsure the bottom case made of PLA will be strong enough to hold the tank. I also plan on using a few internal wood brackets to reinforce it. The outside of the case will be sanded then a coat of Bondo to smooth it out. It will be a lot of finish work, but I would like to see it as smoothed out as possible before paint.
I will likely by a I/O board that I will mount to the top of the case right in front so I have quick access to USB 3.0 ports, audio, and perhaps a eSATA port.
Thanks for stopping by!
