[Build Log] Virtual Cosmos - Cosmos II VR PC

First radiator sleeved





Alright, let's address these motors





Swapped the only white header on there for black



Sleeved the first pump



Screwed up and ripped the ribbon cable solder points



Doing some repair. Soldering in some jumpers



That should work fine



Both done! Not sure if I'll keep the backs blank or not. I'm a big fan of minimalism.



Finished pump assembly. Since I'm doing all custom cabling, I can do things that aren't standard. I'm using the Molex connector for two 12vdc channels in this case for the pumps.

Looks good if you ask me... kind of here for the pics though lol

I figured most people are but the input's always appreciated. Thanks! Trying to work up the motivation to push through this sleeving. It's pretty daunting.

Small update. Used a GPU header for three 12vdc lines. Two are for the pumps and one is for the internal Vive power.

Staple trick

Got around to sleeving the power cables.

DC passthough to Vive








PWM power injection






Looks nice plugged in




Lighting power




Vive and pump power




Aquaero power




More to come!

Better shot of the external Vive ports from the back




Ah ha! Found another white header. Going to rip that apart and replace it




Here's a shot comparing standard sleeving from MDPC on the sides with the fiberglass sleeving in the center. You can see here there's virtually no sheen with the fiberglass which is exactly what I wanted... except a different color, but I'll make it work




Another double USB cable




My internal USB hub looks nice fully populated




Getting the sleeving on the fans. Still need to crimp




Extending the thermistors












Turned out well!




Radiators done. Fans




More to come!

Finally got some time to work on this a bit more. Project isn't dead, just long. I decided to ditch the cable sleeving. The crimps were cutting right through the fiberglass and it wouldn't fit in the smaller headers. I'm going for more of a stealth look now. Trying to hide the cables altogether.

Didn't realize they made a flow meter with USB and Aquabus when I bought the first one. Just need to swap out the white header for black.


Found an Aquabus splitter too. It will be much easier to wire than doing a long chain between the devices. Again, swapping out the white header for black.


This is the way I'll be doing all the cables in the build. Black wire spiral braided (or whatever it's called).


Short 4 pin jumper.


Perfect place to mount my custom power injector for radiator fans. Each radiator has a color code for now but the tape will be coming off when it's complete.


Trying to reduce airflow restriction as much as possible.


Wrapped both temp sensors for each radiator together.


Much cleaner than it could have been!


This monstrocity needs to change. I'm trimming it down and using a 24 pin jumper from it spiral wrapped to clean things up substantially.


Smaller plug from the PSU done.


Much better! Now I can just tuck it in the bottom and jump up to the motherboard.


More to come!

Good to see its still alive an kicking, and with almost vintage hardware soon Jokes aside, looks great.
