Explodable Boxes

[Sanada]

Is it possible to add explodable boxes into CS:S? I might want to add boxes that'll exploded if enough damage is enflicted on them. I just want them to explode with a few wood gibs.

Whoever is near where they go of will recieve some damage (possibly the same as a HE grenade) and if it does kill them it'll report is as a suicide kill.

Would it be best to make the box model out of brushes or a smd model?

Thanks for any imput!
