This is the setup that I was envisioning.......
The hosing would be all 1/2 in. braided vinyl, until I could afford enough tygon (braided vinyl =$.45/ft., tygon=$2.35/ft). The rads would most likely be heater cores (maybe BIXs, but HC are cheaper and better), except for PC4 which would have the DD Cooler Cube that's already in it. The rad/fan units would NOT lay on the PCs just for airflow purposes. PC4 also already has the MAZE3, why use earlier MAZE blocks (honest question Brad)?
Feedback???
