Some awesome folks I know at Gamers Outreach are helping others level up and supporting the troops.  They are giving away a pretty awesome looking Hummer Xbox 360 mod:

"The Xbox 360, enclosed within the Hummer’s shell, is entirely functional and features its own built in monitor, as well as a 250 GB Hard Drive. Chris has fused his passion for supporting the troops with his love of art and video gaming  to shape one of his most impressive pieces of work to date. Simply dubbed “The Hummer,” this modified Xbox 360 Elite has a value of over one thousand dollars in hardware parts alone"

Head on over to the site for a video and the full part list of the hummer, or to donate.  There's additional prizes as well, and you can donate on the site or at the upcoming PAX prime.  I won't be at PAX this year, and that's sad, winning this would cheer me up though.
