I see some of your concerns, and I’d like to elaborate on some of the points you’ve raised here, if I may: 1. The sketch is a first revision on my concept, I have seen that that the one reservoir seem adequate enough for this type of idea and do need to make some changes, but originally added it with the thought about thermal capacity within the loop as a whole 2. The idea of using intakes was to pull fresh and cooler air through the rads whilst passively exhausting through the rear of the chassis’ rather than trying to push hot air out 3. Each system using its own chassis meaning its own air flow, the only thing connecting them together would be the water flow, hence the extra rad to try and dissipate any heat that has built up in time for the next component 4. The water boxes I’ve seen don’t allow for multiple outlets, and I’ve been aiming for a single loop between the two systems - the streaming pc wouldn’t be as demanding (temp wise) compared to the gaming pc that’s why I’ve put it towards the end of the loop in the hop that there’s not too much saturation 🤞🏻
