Hi,
As I'm stuck in the house like the rest for the world I've started to mod an old apple g4 case for a Hackintosh, and everything went ok, but this case it really limited on air flow in that the are 2 possibe fan locations one at the bottom of the case and one in the middle. I've stuck with the bottom as its not obstructed and there is about 3cm clearance. The issue is its getting toasty in there so I've not sure is it best to bring cooler in where there is limited flow out or shout I extract the the air out of the case? I've using a Noctua NF-A14 industrialppc-3000 PWM fan which I'm assuming is a good fan.
