Chiller will be in the cabinet as well
. It will be situated at the right-most part of the equipment cabinet.
The backpanel of the chiller is intentionally left exposed - I will need to use some simple plastic panels to fabricate an 'exhaust tunnel' for the chiller so that expelled warm air does not re-enter the cabinet.
Air is drawn in from a large square cutout at the left corner of the lower cabinet so that the air going in to the cabinet is relatively cooler. The air intake is about 8-9 feet away from the exhaust. I may add a fan at the intake portion.
Lighting
I am still uncertain of how I can hang the lights. I have a used set of lights that does not have a hanging kit. May need to drill holes to do so - or purchase a new set of lights with come with proper hanging kit. I will use the light stands in the beginning.
