It sits nicely either flat or on it’s edge. When on it’s edge the fan is blowing upwards so it will work with convection.
It’s 12×11″ deep so it will also stack with my other cabinets.
It makes a big difference as the electronics wont short as easy and now I can move it around better.
The one thing I forgot is to make holes for air intake. I guess when I make the cover I’ll have to put some vents in it. Perhaps right above the power supply, so the air comes in there, goes through the power supply, then over the heat sinks on the controller, then out the fan port.
