I think that everyone is missing the point... he is runnin a slotket, and those are the CPU that stick out over the mobo. I would possible worry about 400g on that sucker, unless I had something to counterbalance it. Now, I guess it does depend on how tall your processor is sticking off the mobo... really, I think it depends on how you call it. If it feels stable, and rock-solid, then more than likely it is on there good enough. Other wise, try counter-weighting it.
