I was able to shoehorn it into a older Malibu power supply case that has a built in time clock and terminal strip. The voltage supply is very stable. There is a very small amount of noise from the cooling fan which is on all the time. Doesn't bother me a bit but might be a consideration if used indoors. Still - 40 amps for $29?? Can't beat that!
