MojoKid writes "At last count, Activision Blizzard pegged the number of World of Warcraft subscribers at 10.2 million. It takes a massive amount of gear to host all the different game worlds, or realms, as they're referred to. Each realm is hosted on its own server, and in late 2011, Activision Blizzard began auctioning off retired server blades from the days of yore to benefit the St. Jude Children's Research Hospital. They sold around 2,000 retired Hewlett-Packard p-Class server blades on eBay and donated 100 percent of the proceeds (minus auction expenses) to the St. Jude Children's Research Hospital, which seeks to advance the treatment and prevention of catastrophic diseases in children. This article has a look at one of those retired server blades."
