Jack informed about these when they were on sale the first time, because they are so close of a match to the Halo system. I purchased two of them and it was a good decision, by having one in each rack system it has really simplified the powering of the components, out of the 24 power outlets I still have 8 still available for future needs. Also they are rack mountable which is usually not seen on home electronics so it worked out well for mounting them without additional costs.
