If you’re going help save the world, you might as well get a little something for yourself at the same time, right? World of Warcraft fans listen up, because Blizzard wants you to help them help St. Jude Children’s Research Hospital, and it’s willing to give you a fairly unique piece of WoW memorabilia for digging deep. The game developer is once again auctioning off World of Warcraft server blades. This time, the company’s offering up 2,000 HP p-Class blades that were recently retired when it upgraded its backend hardware. The blades, which have gone up for auction on eBay, have been fitted with a clear case bearing the WoW logo and a plaque featuring a slew of developer signatures. One-hundred percent of proceeds will go to help the research hospital.
