SteelSeries, the across-the-pond pro gaming gear outfit, has set up an auction for a bunch of their stuff with the proceeds going to the Red Cross Society of China. I currently have most of the stuff they're putting on the block, and I can for sure recommend the Ikari mouse and the gaming surfaces. Not all the items are up yet so check back for new stuff — they should have a couple headsets there as well in a little while. These guys are keeping track of it as well.
If you're in the market for some new gear (aren't we all, all the time?) and feel like giving a little to charity as well, this is a great opportunity. Thanks to SteelSeries for setting this up, and keep an eye on the site for reviews of their goods in the next couple weeks.
