I got this unit together with a 4U rack a couple of years ago. Mounted on the rear rails it provides power to 4x 1U devices + a WiFi router, all connected via short 0.5 meter IEC cables. This allows for a tidy, rattle-free, compact setup - much better than a regular power strip. Almost perfect for my needs, I just wish it included a few USB ports, even at the expense of a few power ports.
