It's a piece of industrial equipment, sure, but something about the Cambrionix Hub V2 is kind of fascinating. Consider this: With 49 500mAh ports, this USB hub needs its own ATX power supply.
The intended uses for this hub range from the esoteric to the boring: product testing, ad-hoc mega-NASes and group disk manipulation all make the list, while 49-strong Humping Dog orgies somehow don't. Near-unlimited pluggability doesn't come cheap, with the basic hub—without the pictured reinforcement plates or power supply—rings up at about $650. UK-only for now. [Cambrionix—Thanks, Steven!]
