Overclock my Q8200 on an Intel board?

Hi, i haev recently built a little PC for LAN Parties out of spare parts. It uses the case and motherboard from an Acer Aspire M5640. I would like to squeeze as much performance as I can out of it so i was wondering if there is a way to overclock my Core 2 Quad Q8200 on the intel board that came with the PC? Thanks.
