i'm not sure how much performance gain you will get if you are gonna overclock the cpu on a laptop. building a specialized cooling rig for a laptop IMO is not worth it. why can't you just build a desktop? you have a mobility ati radeon 9000 with a single core 2.4ghz intel celeron processor from the specs that i can find. i don't think that the laptop is worth putting a single penny into it. you can probably find a much better laptop w/ gpu for a pretty cheap price if you ( for some reason) have only space for a laptop.
