From the information page on eBay it reads:
Blizzard Entertainment is offering a series of special charity auctions featuring server hardware originally used during World of Warcraftâ€™s early days. Weâ€™ve since upgraded the gameâ€™s infrastructure with the latest technology to offer an even better player experience, but these â€œhonorably dischargedâ€ server blades are now unique collectorsâ€™ pieces.
The net proceeds from the auction will go to benefit
St. Jude Children’s Research Hospital.
