Want to own a piece of Blizzard Entertainment history? After a series of World of Warcraft infrastructure upgrades, we’ve preserved the retired HP server blades that once hosted many realms in our archives. In the near future a selection of these blades will be made available for auction, and the net proceeds will be donated to St. Jude Children’s Research Hospital.
