||This picture shows the controller board. I mounted the
board underneath the harddrive rack facing downwards (this picture is

the side of the case out to the back of the case where it connects to the
PC serial port. The messy wiring you see is for the sensors - I got a bit
lazy towards the end and didn't use terminal blocks like I did for the fan
connectors (which are on the right but not clearly visible).

board underneath the hard drives on the right. The serial port cables run
from the right hand side of the case along the bottom and out on the left
side. I tried to make the wiring a little neater with cable ties for ascetics
as well as for improved air flow.

the bottom intake case fan. I've designated this sensor as the ambient
