The 2011 Rockstar Energy Drink Mayhem Fest is in between lineups right now, as the tour is off season, but the powers-that-be are still working tirelessly. Right now, they are hosting the Mayhem Metal of Honor eBay Auction, the proceeds of which benefit veterans assistance programs.

Tons of items, such as signed drum heads from Machine Head, Trivium and Suicide Silence, as well as an autographed Kingdom of Sorrow drink koozie, are up for grabs and were donated by bands that performed on the 2011 edition of the traveling summer fest.

Go here to check out what's up for auction and if you see something you like, make an bid offer. The funds will go to a good cause and you'll end up with a cool collectible.
