I look at special case like that one but you have to make it your self... I would prefert to use standard part... I don't have a machine shop lol and bending heatpipe and all...
Yea most of us dont access to machine shop LOL
I just wanted you to see how much work a fanless design is
I would suggest that you ask around Toms about the quietest fan available
with one low rpm brushless fan it would be very quiet
just have it at the top exhausting out
