That makes sense. I guess I'll leave the power supply open and contain the driver/controller in a little latch-top box. Maybe I'll build a little shelf into the stand to elevate the power supply and protect it from any accidental spills.
My LDD-1000's at full power get hot. Not crazy hot but still hot. With the PSU it depends on how much load you are pushing. I wouldn't enclose either in anything unless you have active cooling in the enclosure.
