Anyone up for a breathing PC?
It's neat, and does the job. I would add dust filtration for the intakes, I feel like that will build up a ton.
The water-cooling loop itself is a bit iffy, there is no space for the liquid to expand if the heat starts to accumulate. Also the cooling itself only has the ability to be on or off, there is little adjusting it.
But all in all, it's unique and seems to work.
I would prefer using one of these though.
I would just make a traditional build without fans, add on an external radiator as above. Similar size, less pumps (1 or 2 for the whole thing), can work with just water being circulated in the main loop, without any airflow manipulation. Can also add a fan into the external tower and have it in a separate space with lengthy tubing.
It just wouldn't be as unique as a "breathing" PC.
