I would say that some big core router manufacturers have built equally cool looking designs, for things like the Juniper T640, Cisco CRS1 and similar. Also the big Infinera DWDM platforms. The aesthetic is best when people who really care about good quality singlemode do careful cable management on the front line card side.

My least favorite old telecom equipment is probably the Nortel DS3 microwave radio systems, full rack sized, which were the most ugly shade of dark brown.
