A friend gave me a Microstar 6117 LX board, so I thought, well, I might as well build a spare system. So I got a Celeron 300A for it.

The cpu fits pretty snug as it goes pretty deep in the slot--however, I would rather have the retention mechanism in place. Where can I get one? I saw on NECX they had one by Aopen for $1.95, but is that only for Aopen boards, or are these things pretty generic?

Thanks!
