How to edit product boxes?

[Nima]

Looking at the product listings on this category, I want to change the height and placement of some parts in the product boxes.

I dont want to simply change positions of the Price or Title, etc. I want to be able to edit that box.

Can someone tell me which file I should edit?

Thanks

Thanks
