Running a charity stream, looking for hardware donation contacts

Hey everyone,
I’m setting up a charity stream with some friends. We made Bodhis sound repair for Payday 2, and are looking to do a stream for Childs play sometime in the next few weeks. We’ve already got a bunch of prizes lined up ( payday 2 keys/ dlc keys, and a pile of other secret giveaways ). We were hoping to get a few hardware vendors online to perhaps give away a video card or two. We’re planning on sending emails to newegg / ncix and the like to ask, but are there any other people I should contact? I know Logan and Wendel have done a few giveaways so I figured there might be some insight as to who to ask.

Thanks,
